Read the Edited Video Transcript for ‘Fixing Nikon Microscope Stage Wobble’

Hey, this is Chad with Munday Scientific. Today, we’re going to talk about a common problem found on several Nikon microscope models involving the stage locking screw.

This is an issue we see quite frequently, and it can cause the microscope stage to become loose, wobble, or rotate when it should be securely locked in position.

Fortunately, we’ve developed a simple replacement that provides a more durable, long-term solution.

The Problem With the Original Nikon Stage Locking Screw

The original Nikon stage locking screw has a spring-loaded pin with a plastic tip.

When you remove the screw from the microscope, you can see the small plastic piece at the end of the plunger.

Over time, this plastic tip can crack, wear down, or break off completely.

It’s a common failure point on these microscopes.

When the plastic tip becomes damaged, the locking screw may no longer apply sufficient pressure to hold the stage securely.

You can tighten the screw, but because part of the plastic tip is missing, the stage may still wobble or rotate.

This can be frustrating, especially when you’re trying to examine specimens or move slides accurately.

Identifying a Damaged Stage Locking Screw

If your Nikon microscope stage feels loose, one of the first things you should check is the stage locking screw.

Carefully remove the screw and inspect the spring-loaded tip.

If the plastic end is cracked, partially missing, or completely broken off, you’ve likely found the problem.

In our demonstration, you can see the exposed metal pin where the plastic tip has failed.

Even though the screw itself may still be in good condition, the damaged tip prevents it from gripping the stage properly.

Repairing the Original Screw

One option is to rebuild the original locking screw.

This involves disassembling the screw assembly, removing the retaining C-clip and pin, and replacing the damaged plastic plunger tip.

While this can restore the original assembly, it requires several small components and additional work.

And because the replacement tip is still plastic, it remains a potential wear point.

Our All-Steel Replacement Stage Locking Screw

At Munday Scientific, we’ve developed an all-steel replacement stage locking screw that eliminates the original plastic tip.

Instead of rebuilding the old screw, you can replace the entire assembly with our updated version.

The advantage is that there’s no plastic tip to crack or break off again.

It’s a straightforward replacement designed to provide a more durable solution to this common problem.

Compatible Nikon Microscope Models

Our replacement stage locking screw is designed for several popular Nikon microscopes, including:

• Nikon E400
• Nikon E600
• Nikon 50i
• Nikon 55i
• Nikon Ci series

These microscopes use similar stage locking arrangements, making the replacement a convenient option for a variety of Nikon models.

Installing the Replacement Screw

Installation is very simple.

First, remove the original stage locking screw from the microscope.

You’ll notice that these screws have relatively long threads, so it may take several turns to remove the old screw completely.

Once it’s removed, take the new all-steel replacement and carefully thread it into the same opening.

Make sure the screw is properly aligned with the threads before tightening.

Continue turning the screw until it makes contact and securely locks the stage in place.

You don’t need to overtighten it. Just make sure the stage is held firmly.

Testing the Stage

Now that the replacement screw is installed, let’s check the stage.

With the screw loosened, the stage can move or rotate.

Once we tighten the new locking screw, the stage becomes secure and no longer rotates.

That’s exactly what we want.

The new screw provides a firm connection without relying on the original plastic-tipped plunger.

Properly Aligning the Microscope Stage

While we’re working with the stage, there’s another important tip I’d like to share.

Whenever you’re installing or repositioning a Nikon microscope stage, you want to make sure it’s properly squared with the microscope.

If the stage is installed at an angle, you may notice that the specimen moves diagonally across the field of view when you’re scanning in the X or Y direction.

For example, when you move the mechanical stage horizontally, the specimen may appear to travel at an angle rather than moving straight across the viewing field.

This can indicate that the stage isn’t aligned correctly.

Using a Microscope Slide to Square the Stage

Here’s a simple technique we use to help align the stage.

Start by slightly loosening the stage locking screw.

Take an old microscope slide and position it behind the stage as a straightedge against the microscope’s reference surface.

Gently push the stage backward until it’s properly aligned.

Once the stage is square, tighten the locking screw to secure it.

This helps ensure that the stage is positioned correctly before you begin examining specimens.

It’s a quick procedure that can make a noticeable difference in how the stage tracks during use.

Troubleshooting Diagonal Stage Movement

If you’re scanning a slide and notice that the specimen moves diagonally instead of following the expected horizontal or vertical direction, check the stage alignment.

A crooked stage is one possible cause.

Depending on the microscope configuration, the orientation of the viewing head may also affect how stage movement appears through the eyepieces.

Before assuming there’s a mechanical problem with the stage controls, verify that the stage is installed squarely and that the viewing head is properly positioned.

Final Thoughts

The broken plastic tip on the original Nikon stage locking screw is a common problem, but it’s also relatively easy to correct.

Rather than rebuilding the original spring-loaded assembly, our all-steel replacement screw provides a simple, durable alternative.

Once installed, it securely locks the stage and eliminates the wobbling or rotation caused by a damaged locking tip.

And whenever you’re installing or adjusting a microscope stage, take a moment to make sure it’s properly squared with the microscope.

That can help prevent frustrating alignment problems when scanning specimens.

Read the Edited Video Transcript for ‘Olympus BX Microscope Stage with Install Tips’

Hey, this is Chad with Munday Scientific. Today, we’re going to talk about the different stage options available for Olympus BX-series microscopes, including how to remove and replace a stage and how to avoid one of the most common installation problems.

One of the great features of the Olympus BX series is that the stage can be removed and replaced relatively easily. This allows you to configure the microscope to suit your particular application and working preferences.

Olympus BX Stage Options

There are several stage configurations available for Olympus BX microscopes.

Right-Hand Mechanical Stage

This configuration has the mechanical stage controls positioned on the right side of the microscope. It allows you to move the slide precisely using the coaxial stage controls.

Left-Hand Mechanical Stage

The left-hand version operates the same way, but the stage controls are positioned on the opposite side.

This can be a more comfortable option depending on your preferred working position.

Fixed Stage

A fixed stage is another popular option, particularly among pathologists who prefer to move their slides manually.

Instead of using mechanical stage controls and a slide holder, the operator simply pushes the slide across the stage with their fingers.

Fixed stages are also considerably less expensive than mechanical stages.

At the time of this video, a fixed stage typically costs approximately $350–$400, while a mechanical stage can cost around $700 or more, plus the slide holder.

Removing the Olympus BX Stage

Let’s demonstrate how easy it is to remove the stage.

First, lower the microscope stage completely using the coarse focus adjustment.

This creates additional clearance between the stage and the objectives.

Next, locate the retaining screw that secures the stage to the microscope.

On this particular stage, there’s a convenient thumbscrew that can be loosened by hand.

Once the screw is loose, carefully lift the stage away from its mounting position.

Be sure to avoid contact with the objectives or the condenser’s top element.

If your microscope has a swing-out condenser, you can move the top element out of the way for additional clearance.

You can also lower the condenser if necessary.

The important thing is to remove the stage slowly and carefully so you don’t damage any of the optical components.

Different Stage Retaining Screws

There are two common retaining screw configurations you’ll encounter on these stages.

Some use a thumbscrew, like the stage we just removed.

Others use a 3 mm Allen-head retaining screw.

Both styles perform the same function, securing the stage to its mounting bracket.

The installation procedure is essentially identical regardless of which screw type your stage uses.

Installing the Replacement Stage

Now let’s install another stage.

One of the most important tips I can give you is to back the retaining screw out completely before positioning the stage.

This helps ensure that the stage can sit properly and evenly on its mounting surface.

Carefully lower the stage into position, making sure it is fully seated and sitting flush.

Once you’re confident that the stage is positioned correctly, tighten the retaining screw to lock it in place.

It sounds simple, but this is where one of the most common problems occurs.

Why Proper Stage Alignment Is Important

Sometimes a stage can appear to be installed correctly even though it isn’t fully seated.

If the retaining screw hasn’t been backed out far enough, the stage may catch on the mounting bracket and sit slightly crooked.

You can tighten the screw, and the stage may feel completely secure, but it will still be misaligned.

This can create noticeable focusing problems, particularly at higher magnifications.

For example, when using a 20X, 40X, 50X, 60X, or 100X objective, you may notice that one side of the specimen is in focus while the other side is out of focus.

One possible cause is that the stage was installed unevenly.

Before assuming there’s a problem with your objectives or microscope optics, check that the stage is properly seated.

How to Make Sure the Stage Is Seated Correctly

Let’s look at what happens when the stage isn’t positioned correctly.

If you place the stage onto the mounting bracket without fully backing out the retaining screw, it may stop before reaching its proper position.

You might think the stage is seated, but it can actually be resting slightly above or at an angle to the mounting surface.

If you tighten the screw in that position, the stage will lock down crooked.

To avoid this, loosen the retaining screw completely, reposition the stage, and make sure it drops fully into place.

Only then should you tighten the screw.

Using a Microscope Slide to Square the Stage

Here’s another trick I like to use when installing an Olympus BX stage.

Take an old microscope slide and place it on the stage.

With the stage retaining screw slightly loose, position the slide so you can use it as a straightedge against the microscope’s reference surface.

Gently push the stage into alignment using the slide as a guide.

Once the stage is properly squared, tighten the retaining screw.

This is a simple way to help ensure that the stage is positioned evenly and isn’t sitting at an angle.

Removing the Slide Holder for Manual Operation

If you already have a mechanical stage but prefer to move your slides manually, you may not need to purchase a completely different stage.

On many Olympus BX mechanical stages, the slide holder can be removed.

Simply locate the knurled screws that secure the slide holder to the stage.

Loosen those screws and slide the holder off.

With the slide holder removed, you can move the specimen slide directly with your fingers.

This is a convenient option for pathologists who prefer manual slide movement but don’t want to invest in a separate fixed stage.

Choosing the Right Stage for Your Application

The best stage configuration really comes down to how you prefer to use your microscope.

If you want precise, controlled slide movement, a mechanical stage with either right-hand or left-hand controls is an excellent choice.

If you’re a pathologist who prefers to move slides by hand, a fixed stage may be more comfortable and economical.

And if you already have a mechanical stage, removing the slide holder may give you the manual operation you’re looking for without replacing the entire assembly.

That’s one of the advantages of the Olympus BX series. These microscopes offer a lot of flexibility and are easy to configure for different users.

Final Thoughts

Changing the stage on an Olympus BX microscope is a straightforward procedure, but proper installation is extremely important.

Always lower the stage before removing it, provide adequate clearance around the objectives and condenser, and make sure the retaining screw is fully backed out before installing the replacement.

Most importantly, verify that the stage is sitting completely flush before tightening it down.

A stage that is slightly crooked can cause frustrating focusing problems, especially at higher magnifications.

Taking a little extra time during installation can save you a lot of troubleshooting later.

Read the Edited Video Transcript for ‘How to Fix a Blurry 40X Microscope Lens’

Hey, this is Chad with Munday Scientific. Today, we’re going to demonstrate how to properly clean immersion oil off a 40X microscope objective.

This is a common problem, particularly in veterinary laboratories where microscopes are frequently used with 100X oil immersion objectives.

If you’ve ever noticed that your 40X objective suddenly produces a cloudy, milky, or blurry image, there’s a good chance that immersion oil has gotten onto the front lens.

Let’s take a look at how that happens and how to clean it.

How Oil Gets on the 40X Objective

When examining specimens using a 100X oil immersion objective, you’ll typically place a drop of immersion oil on the coverslip before bringing the objective into position.

After examining the specimen at 100X, it’s easy to forget that the oil is still on the slide.

If you rotate the nosepiece back to the 40X objective, the front lens may come into contact with the remaining oil.

Unlike the 100X oil immersion objective, the 40X is typically a dry objective, meaning it isn’t designed to be used with immersion oil.

When oil contaminates the front lens, the image can become cloudy, hazy, or milky, significantly reducing image clarity.

Fortunately, this is usually something you can clean yourself.

Step 1: Lower the Microscope Stage

The first thing you want to do is lower the microscope stage completely.

This creates additional clearance between the objectives and the specimen, helping prevent accidental contact or damage.

Next, rotate the 40X objective into a position where you can comfortably access it.

Step 2: Remove the 40X Objective

Carefully unscrew the 40X objective from the microscope nosepiece.

I recommend using both hands whenever possible to keep the objective secure.

Once the objective has been removed, turn it upside down so you can access the front lens.

This is the small lens at the tip of the objective that may have come into contact with the immersion oil.

Step 3: Prepare Your Cleaning Supplies

For cleaning immersion oil, I like to use a product called Residual Oil Remover (ROR).

It’s a lens-cleaning solution that works well for removing oil and other contaminants from optical surfaces.

We carry ROR through our online store, and it’s also available from other retailers.

You’ll also need a cotton swab. I personally prefer Q-tips brand cotton swabs for this procedure.

Some people use Kimwipes, but I’ve found that Q-tips work particularly well for cleaning the small front lens of a microscope objective.

Make sure you’re using a clean swab and a lens-cleaning solution that’s appropriate for microscope optics.

Step 4: Clean the Front Lens

Apply a small amount of lens cleaner to one end of the cotton swab.

You don’t need to saturate the swab. Just use enough cleaner to gently remove the oil.

Carefully wipe across the front lens in one direction.

Then turn the swab around and use the clean, dry end to wipe across the lens again.

One important tip is to avoid rolling the cotton swab while wiping.

If you roll the swab, you may transfer oil from the contaminated portion of the cotton back onto the lens.

Instead, make a gentle pass across the lens using a clean section of the swab.

Step 5: Repeat the Cleaning Process

After the first pass, rotate the objective slightly in your hand and repeat the cleaning process.

Use a fresh, clean section of the cotton swab as needed.

I like to clean the lens from several different directions to make sure all the oil has been removed.

You may need to repeat the process a few times, depending on how much immersion oil is present.

The goal is to remove the oil without scratching the lens or leaving residue behind.

Use gentle pressure and avoid excessive rubbing.

Step 6: Inspect the Objective Lens

Once you’ve finished cleaning, it’s a good idea to inspect the front lens before reinstalling the objective.

One convenient way to do this is by using a microscope eyepiece as a magnifier.

On some microscopes, the eyepieces are held in place by small retaining screws.

For this particular microscope, we’re using a 1.5 mm Allen wrench to loosen the eyepiece retaining screw.

Many microscopes don’t have their eyepieces secured this way, so you may be able to remove yours without a tool.

Once the eyepiece is removed, turn it around and look through it backward, using it much like a jeweler’s loupe.

Hold the eyepiece a short distance from the objective’s front lens and adjust the distance until you can clearly see the lens surface.

It may take a little practice to find the correct viewing distance, but once you do, you’ll be able to inspect the front lens for remaining oil, dust, or other contamination.

In our demonstration, the lens looks perfectly clean.

Step 7: Reinstall the Objective

Once you’re satisfied that the lens is clean, carefully screw the 40X objective back into the microscope nosepiece.

Make sure the objective is properly threaded and securely seated.

Before returning to the 40X objective, make sure you’ve removed any remaining immersion oil from the specimen slide.

Otherwise, you may accidentally contaminate the objective again.

Step 8: Check the Image Quality

Now we’re ready to test the objective.

I find it easiest to start by lowering the stage and bringing the specimen into focus using the 10X objective.

Once you’ve achieved a sharp image at 10X, rotate the nosepiece to the 40X objective.

Make any necessary fine-focus adjustments and check the image.

If the oil has been completely removed, you should see a clear, sharp image again.

That’s all there is to it.

Tips for Preventing Oil Contamination

One of the best ways to avoid this problem is to develop a consistent routine when switching between dry objectives and oil immersion objectives.

Always remember that oil may remain on the slide after using the 100X objective.

Before returning to the 40X, check the slide and remove any remaining immersion oil using an appropriate cleaning method.

Also, avoid forcing an objective into position if there isn’t enough clearance between the lens and the slide.

Keeping your objectives clean and using the proper cleaning supplies will help maintain image quality and protect your microscope optics.

Final Thoughts

Cleaning immersion oil off a 40X objective is a relatively simple process, and it’s something that many microscope users can perform themselves.

The key is to use an appropriate optical cleaning solution, a clean cotton swab, and gentle, controlled wiping motions.

Remember to avoid rolling the swab across the lens, since that can transfer oil right back onto the surface you’re trying to clean.

If the image is still cloudy after cleaning, the objective may need additional inspection or professional servicing.

View the Edited Video Transcript for ‘Mastering the Olympus BH2 Microscope’

Hey, this is Chad with Munday Scientific. Today, we’re going to take a look at the Olympus BH2 microscope, a classic instrument that remains popular among microscope users.

This is an oldie but a goodie. The BH2 was one of the microscopes that helped establish Olympus as a major competitor in the clinical microscopy market, competing with manufacturers such as Leitz Wetzlar.

Even today, the BH2 is an excellent microscope.

This particular microscope was recently purchased by a customer and has been fully refurbished. We’re going to go over some of its features, discuss the different components, and demonstrate how to disassemble and reassemble it.

Trinocular Head and Camera Adapter

We’ll start with the trinocular head.

This microscope is equipped with a V-clamp and a Diagnostic Instruments camera adapter. The adapter has a focusable adjustment and is secured with two screws.

When these microscopes were originally introduced, 35 mm film cameras were commonly used for photomicrography. Today, different adapters can be installed to accommodate modern C-mount microscope cameras.

The trinocular head operates very similarly to those found on newer Olympus BX-series microscopes.

It has a pull rod that controls the light distribution between the eyepieces and camera port.

Depending on the position of the pull rod, you can direct the light entirely to the eyepieces, split the light between the eyepieces and camera, or direct 100% of the light to the camera.

This particular head has been completely relubricated by an authorized Olympus service technician, so all the adjustments operate smoothly.

Eyepieces and Diopter Adjustments

The microscope has 10X eyepieces with a 20 mm field of view.

One side of the trinocular head has a built-in diopter adjustment, allowing you to focus that eyepiece independently.

The other side has a focusable eyepiece with its own adjustment.

You’ll notice a small locating pin on the focusable eyepiece that fits into a corresponding notch in the eyepiece tube. This keeps the eyepiece properly positioned and allows you to adjust its focus without the entire eyepiece rotating.

It’s a convenient feature that makes focusing easier.

Standard Binocular Head Option

Another common configuration for the Olympus BH2 is the standard binocular head.

To remove the trinocular head, simply loosen the retaining screw and carefully lift the head away from its dovetail mount.

The standard binocular head attaches in the same location.

Many BH2 microscopes were originally supplied with this conventional binocular configuration.

Both head styles work well, and the choice depends on whether you need a camera connection.

Nosepiece and Objective Removal

Unlike some newer Olympus microscopes, the nosepiece on this BH2 is not designed to be removed as a separate assembly during routine maintenance.

To remove an objective, first lower the stage completely.

This provides additional clearance and helps prevent accidentally scratching an objective or damaging a slide.

Once the stage is lowered, carefully unscrew the objective from the nosepiece.

Reinstallation is just as simple. Thread the objective back into its position and make sure it is securely seated.

Phase Contrast Objectives

This particular BH2 is configured for phase contrast microscopy.

You’ll notice that one of the objectives is marked SPlan 10X PL.

The PL designation identifies it as a phase contrast objective in this configuration.

Phase contrast objectives work with corresponding annular diaphragms in the condenser to enhance contrast in transparent specimens.

A standard brightfield objective generally won’t have the same phase designation.

Mechanical Stage and Slide Holder

Next, we’ll remove the mechanical stage.

Start by lowering the stage completely and making sure there’s enough clearance between the stage and the objectives.

The slide holder can be removed by loosening the two knurled screws that secure it to the stage.

One common issue with older Olympus BH2 stages involves the plastic racks used in the mechanical stage movement.

Over time, these racks can develop small hairline cracks as the plastic ages.

When this happens, you may notice that the stage movement feels uneven, almost as though it’s going over a speed bump.

On this microscope, the original racks have been replaced, and the coaxial stage controls have been completely relubricated.

As a result, the stage movement is smooth and feels like new.

Replacement stage racks are available through our online store.

Phase Contrast Condenser

Underneath the stage, we have a phase contrast condenser.

The condenser has different phase annulus positions that correspond to the microscope’s phase objectives.

For example, the 10X phase objective uses its matching 10X phase position. The same principle applies to the 20X, 40X, and 100X phase objectives, using the appropriate matching condenser settings.

The condenser also has a zero position, which is used for standard brightfield observation.

Properly matching the condenser annulus to the phase objective is essential for achieving the intended phase contrast image.

Field Diaphragm and Daylight Blue Filter

The Olympus BH2 has a field diaphragm that is used when setting up proper illumination.

It also has a daylight blue filter.

Because this microscope uses a halogen illumination system, the light naturally has a warmer, slightly yellow appearance.

The daylight blue filter helps reduce that yellow hue and produces a cooler, more neutral appearance when viewing specimens.

Halogen Lamp and Socket

The BH2 uses a halogen illumination system, and we’ve covered bulb replacement in another video.

This particular microscope has a new bulb installed.

The lamp assembly also includes a reflector that helps direct light into the microscope’s illumination system.

Olympus produced different BH2 configurations, including the higher-powered BHS version, which uses a 12V, 100W illumination system.

These microscopes provide excellent illumination and remain very capable instruments.

Coarse Focus Tension Adjustment

Another important feature of the BH2 is its coarse focus tension adjustment.

The tension collar allows you to control how freely the stage moves when using the focus controls.

If the tension is too loose, the stage may gradually drift downward under its own weight.

If the tension is too tight, focusing can become unnecessarily difficult.

To adjust the tension, use the appropriate tool in the adjustment collar and rotate it in the required direction.

Moving the adjustment one way increases tension, while moving it the opposite way reduces tension.

The goal is to achieve smooth focusing while maintaining enough resistance to prevent the stage from drifting.

Focus Stop Adjustment

The BH2 also includes a focus stop mechanism.

This allows you to establish an upper limit for stage travel.

Once the stop is set, the stage cannot be raised beyond that predetermined position without releasing or adjusting the stop.

This is especially useful for preventing the objective from accidentally contacting a slide.

The focus stop and tension adjustment work together to provide controlled, predictable stage movement.

Removing and Reinstalling the Condenser

Now let’s take a look at the condenser mounting system.

The condenser is held in place by a retaining screw in the substage assembly.

Loosen the screw and carefully remove the condenser.

You’ll notice a locating pin on the condenser that corresponds with a notch in the mounting bracket.

When reinstalling the condenser, position it so the pin enters the appropriate opening.

Rotate the condenser gently until you feel it settle into its proper position.

Once it’s seated, secure the retaining screw.

The condenser is now ready to be centered and aligned.

Setting Köhler Illumination

After reinstalling the condenser, you’ll want to set Köhler illumination.

We have another video demonstrating that procedure in detail.

For this microscope, we recommend beginning the Köhler illumination setup using the 10X objective.

Proper Köhler illumination helps provide even illumination across the field of view and allows the microscope’s optical system to perform as intended.

Centering the Phase Contrast Rings

The phase contrast condenser also has small adjustment pins used for centering the phase annuli.

These adjustments are important because the condenser annulus must be properly aligned with the corresponding phase ring in the objective.

Unless you’re familiar with the phase contrast alignment procedure, it’s best not to adjust these pins unnecessarily.

On this particular microscope, the phase contrast condenser turret has been relubricated, and the phase rings have already been centered.

Everything is operating properly and is ready for use.

Reassembling the Olympus BH2

Now that we’ve reviewed the components, let’s put the microscope back together.

Reinstalling the Slide Holder

Start by reinstalling the slide holder onto the mechanical stage.

Align the mounting points and tighten the two knurled screws.

Reinstalling the Stage

Lower the microscope’s focus mechanism to provide adequate clearance.

Carefully position the stage onto its mounting surface.

Make sure the stage is sitting flush before tightening the retaining screw.

Reinstalling the Head

Next, position the trinocular head onto the microscope’s dovetail mount.

Make sure the mounting flange is properly seated beneath the retaining surfaces.

Once everything is aligned, tighten the retaining screw securely.

Always support the head until you’re certain it’s locked in place.

Reinstalling the Eyepieces

Install the non-focusable eyepiece into the tube with the built-in diopter adjustment.

Then install the focusable eyepiece into the opposite tube, making sure its locating pin fits into the corresponding notch.

Reinstalling the Camera Adapter

Finally, slide the camera adapter back into the trinocular head’s camera connection.

Position it correctly and tighten the two retaining screws.

The microscope is now fully reassembled.

Why the Olympus BH2 Is Still an Excellent Microscope

The Olympus BH2 is one of those classic microscopes that has stood the test of time.

It helped establish Olympus as a major manufacturer in the clinical microscope market, and many of these instruments are still being used today.

With proper servicing, relubrication, and replacement of worn components, a BH2 can continue providing excellent optical performance.

This particular microscope has been fully refurbished, including the trinocular head, mechanical stage, phase contrast condenser, and illumination components.

It’s a great example of how well these microscopes were originally built.

We’ll be producing more videos covering the Olympus BH2 and its various components.

Read the Edited Video Transcript for ‘Replace the LS30 Lamphouse on a BX Microscope’

Hey, this is Chad with Munday Scientific. Today, we’re going to talk about the lamp housings used on the Olympus BX40 microscope, including how to identify the original lamp housing, recognize potential problems, and install the updated replacement.

Original Olympus U-LS30 Lamp Housing

The original lamp housing used on the Olympus BX40 is the U-LS30.

You’ll notice that this original lamp housing has a fairly simple, square-shaped design.

The halogen bulb fits into the socket inside the housing, which then attaches to the rear of the microscope.

This system uses a 6V, 30W halogen bulb.

The original U-LS30 lamp housing is no longer manufactured, so if you’re looking for a replacement, you’ll want to use the updated version.

Updated U-LS30-4 Lamp Housing

The replacement lamp housing is the Olympus U-LS30-4.

Although it looks different from the original square-shaped U-LS30, it serves the same purpose and is designed to work with the Olympus BX40.

The updated lamp housing includes an improved socket assembly and a heat filter.

It also uses the same 6V, 30W halogen bulb.

We frequently get questions from customers who notice that the replacement lamp housing doesn’t look like the original one on their microscope.

That’s perfectly normal. The U-LS30-4 is the updated replacement design.

Troubleshooting a BX40 With No Illumination

One common issue we see with the Olympus BX40 involves the microscope powering on but producing no illumination.

There are several possible causes, including:

• A burned-out halogen bulb
• A defective lamp socket
• A missing or disconnected lamp housing
• A missing bulb

Here’s a useful troubleshooting observation.

If you turn on the microscope and the illumination indicator remains fully illuminated, but the light intensity cannot be adjusted, that may indicate a problem with the bulb or lamp housing assembly.

For example, if the lamp housing is completely disconnected, you may see this behavior even though the microscope itself is receiving power.

It’s a good indication that you should inspect the bulb, socket, and lamp housing connections.

Removing the Original Lamp Housing

Replacing the lamp housing is a relatively simple procedure.

First, turn the microscope off and unplug it from the electrical outlet.

Allow the lamp housing and bulb to cool completely before handling them.

At the rear of the microscope, locate the existing lamp housing.

Place your fingers along the sides of the housing, press inward as needed to release it, and gently wiggle the assembly while pulling it away from the microscope.

The lamp housing should slide out of its mounting connection.

Once removed, you can inspect the socket and bulb or replace the entire assembly.

Installing the Replacement U-LS30-4

Now we’ll install the updated lamp housing.

The replacement has alignment pins and guideways that correspond with the mounting connection on the microscope.

These guides make it easy to position the lamp housing correctly.

Align the pins with the appropriate openings and gently press the replacement housing into position until it is fully seated.

There’s no need to force the assembly. When everything is aligned properly, it should fit securely into place.

Testing the New Lamp Housing

Once the new lamp housing has been installed, reconnect the microscope to its power source.

Turn the microscope on and check the illumination.

In our demonstration, the microscope originally had no lamp housing installed, and the illumination indicator remained fully illuminated.

After installing the replacement housing with a working bulb and socket, the microscope illuminates normally again.

This confirms that the new lamp housing is functioning properly.

Replacement Halogen Bulbs

The Olympus BX40 uses a 6V, 30W halogen bulb.

If your lamp housing is still in good condition and only the bulb has failed, you may not need to replace the entire assembly.

Replacement bulbs are available separately and can be installed in the existing compatible lamp housing.

We’ll include a link to the correct replacement bulb in the video description.

Why the Replacement Looks Different

One of the most common questions we receive is why the replacement lamp housing doesn’t look like the original.

The original U-LS30 has a square-shaped housing, while the updated U-LS30-4 has a different design.

Even though the appearance has changed, the replacement performs the same basic function and is intended to replace the older assembly.

If you’re searching online for the original U-LS30, you may have difficulty finding one. And if you do locate one, it’s likely to be an older, used component.

For that reason, we recommend using the updated replacement when appropriate.

Final Thoughts

If your Olympus BX40 microscope powers on but the halogen illumination isn’t working, start by checking the bulb and lamp housing.

A failed bulb, defective socket, or disconnected lamp housing may be responsible for the problem.

Replacing the original U-LS30 with the updated U-LS30-4 can be a straightforward way to restore illumination without replacing the microscope.

Read the Edited Video Transcript for ‘Install a Micrometer Reticle in Your Eyepiece’

Hey, this is Chad with Munday Scientific. Today, we’re going to show you how to install a reticle in an Olympus microscope eyepiece.

This procedure is very similar for most microscope eyepieces, including Nikon models. We’re using an Olympus eyepiece for this demonstration because Olympus and Nikon are two of the most common microscope brands we work with.

Understanding the Focusable Eyepiece

For this demonstration, we’re using a focusable eyepiece, which is particularly useful when installing a reticle.

You’ll notice that the eyepiece has an adjustable section that rotates in and out. This allows you to adjust the focus of the reticle independently.

Inside the eyepiece is a reticle shelf, which holds the glass reticle in position.

Removing the Reticle Shelf

To access the reticle shelf, turn the eyepiece over and locate the threaded retaining assembly.

Sometimes these can be a little stiff. I usually place my thumb inside the opening and carefully rotate the assembly until it unscrews.

Once removed, you’ll see the shelf where the reticle sits.

If you’re ordering a new reticle, you’ll want to measure the diameter of this opening to determine the correct glass disc size.

Reticles are also commonly called eyepiece micrometers, particularly when they’re used for measuring specimens.

Preparing the Reticle for Installation

Before installing the reticle, it’s important to make sure the glass is completely clean.

These small glass discs attract dust and fingerprints very easily. Even a tiny speck of dust can become extremely noticeable when magnified through the microscope.

For this procedure, we have a few cleaning supplies available:

• Kimwipes
• Optical lens cleaner
• Canned air or an appropriate optical air duster

I typically start with the air duster.

Before spraying the reticle, I briefly test the air duster away from the optics to make sure it isn’t releasing any liquid or residue.

Hold the reticle carefully by its edges to avoid touching the glass surfaces.

Then gently blow away any dust or loose particles from both sides.

Be thorough, because even one small speck of dust can look enormous when viewed through the microscope.

Installing the Reticle

Once the reticle is clean, inspect it to determine its proper orientation.

Some reticles have markings or numbers that need to face a particular direction so they appear correctly when viewed through the eyepiece.

Carefully place the reticle onto the shelf, making sure it sits flat and is properly positioned.

Then reinstall the retaining assembly by threading it back into the eyepiece.

Avoid overtightening the assembly.

Checking the Reticle Orientation

After reinstalling the reticle, look through the eyepiece to make sure the markings are oriented correctly.

Sometimes you may discover that the reticle is upside down.

If that happens, simply remove the retaining assembly, reposition the reticle, and reinstall it.

It’s always worth checking before putting the eyepiece back into the microscope.

Looking through the eyepiece also makes it easier to identify any remaining dust or debris on the reticle.

Installing the Focusable Eyepiece

Now we’re ready to put the eyepiece back into the microscope head.

One important thing to remember is that many binocular microscope heads already have a built-in diopter adjustment on one side.

Since our reticle eyepiece is independently focusable, I prefer to install it on the side without the built-in diopter adjustment.

The focusable eyepiece essentially provides its own diopter adjustment, allowing you to bring the reticle markings into sharp focus.

Once installed, the microscope is ready for measuring specimens after the reticle has been properly calibrated.

We’ll cover the calibration process in another video.

Cleaning a Dirty Reticle

If your reticle is especially dirty, blowing it off with air may not be enough.

In that case, you’ll need to clean the glass more thoroughly.

Step 1: Remove the Reticle

Carefully unscrew the retaining assembly and remove the reticle from its shelf.

Always handle the glass by its edges.

Step 2: Apply Lens Cleaner

Use a small amount of optical lens cleaner suitable for coated glass surfaces.

Rather than saturating the reticle, apply a light amount of cleaner to an appropriate lens-cleaning tissue.

Step 3: Wipe the Glass

Gently wipe the glass to remove fingerprints, smudges, or other contamination.

Rotate the reticle as needed to clean the entire surface.

Be careful not to apply excessive pressure or damage the reticle markings.

Step 4: Dry and Inspect

Allow the reticle to dry, or carefully use an optical air duster to remove any remaining particles.

Inspect both sides before reinstalling it.

Step 5: Reinstall the Reticle

Place the clean reticle back onto its shelf, verify its orientation, and reinstall the retaining assembly.

Look through the eyepiece one final time to make sure the reticle is clean, properly positioned, and clearly visible.

KR-207 Reticle Specifications

For this demonstration, we’re using a KR-207 reticle with a diameter of 24 mm.

This reticle is available through our online store, Microscope Marketplace.

If you’re ordering a reticle for your own microscope, make sure you verify the required diameter for your particular eyepiece before purchasing.

Final Thoughts

Installing a reticle in an Olympus or Nikon microscope eyepiece is a relatively simple procedure.

The most important things to remember are to use the correct reticle diameter, keep the glass clean, install it in the proper orientation, and use a focusable eyepiece when appropriate.

Once the reticle is installed, it will need to be calibrated before you can use it for accurate specimen measurements.

We’ll demonstrate that calibration procedure in a separate video.

Read the Edited Video Transcript for ‘Cover Glass Correction Using an Adjustable Objective’

Hey, this is Chad with Munday Scientific. Today we’ve got an Olympus BX41 here with an S Plan Apo 40X objective, and we’re going to talk about coverglass correction collars.

We get a lot of questions about these, so let’s take a closer look at how they work and why they’re important.

What Is a Coverglass Correction Collar?

If you look closely at this objective, you’ll see several numbers on the correction collar representing different coverglass thicknesses.

There’s also a small white scribe mark that shows you where the collar is currently set.

For most applications, you’re going to want that mark set at approximately 0.17 mm. That’s because 0.17 mm is the standard coverglass thickness that you’ll commonly encounter on prepared microscope slides.

However, there’s a reason this collar is adjustable.

Depending on the actual thickness of the coverglass you’re viewing through, the image may look better at a slightly different correction setting. The purpose of the collar is to allow you to compensate for those differences and achieve the best possible image.

What Is the Coverglass?

If you’re not familiar with the terminology, the coverglass, or coverslip, is the thin piece of glass placed over the specimen on the microscope slide.

You can see that this particular slide has a coverslip over the tissue. It’s extremely thin and sits nearly flush with the surface of the slide.

Because you’re viewing the specimen through this glass, variations in its thickness can affect the optical performance of a high-quality objective.

Why the Correction Collar Needs to Move Freely

It’s important that the correction collar on the objective moves properly.

If an objective sits unused for a long period of time, the collar can sometimes become stuck in one position. These can be very difficult to free up without damaging the objective.

If the correction collar is seized, you’ll generally want to have a microscope service professional repair the objective rather than trying to force it.

For this demonstration, we’re going to set the correction collar to 0.17 mm, since that’s the typical coverslip thickness we’re working with.

Installing and Testing the Objective

Now we’re going to install the objective on the microscope and see how the image looks.

We’ll start by locating the specimen at lower magnification and bringing it into focus.

Since we have the 2X objective in place initially, we’ll flip the condenser’s top element out as needed for the low-magnification objective.

Then we’ll move to the 10X objective, bring the specimen into focus, and set Köhler illumination.

We’ll make sure the condenser is properly centered and that the eyepieces are set correctly.

From there, we’ll move through the 20X objective and then up to the higher-magnification objectives.

Checking the 40X Image

Now we’ll move to the 40X objective with the coverglass correction collar that we just set.

And that’s a beautiful image.

In this case, setting the correction collar to 0.17 mm gave us an excellent result.

The important thing to understand is that the ideal setting can vary depending on the thickness of the coverslip. If the image isn’t as sharp as you expect, adjusting the correction collar slightly may improve it.

Use the Nosepiece to Change Objectives

There’s another important point about objectives with correction collars.

Some pathologists and other microscope users like to change objectives by grabbing the objective itself and rotating the nosepiece.

That’s not a good habit when you’re using an objective with a freely moving correction collar.

If the collar is properly lubricated and operating as it should, grabbing the objective can accidentally rotate the correction collar. That changes your setting and can affect image quality, forcing you to continually readjust or refocus the microscope.

Instead, rotate the microscope using the nosepiece itself rather than grabbing the objective.

Periodically check the correction collar as well and make sure it’s still set where you want it—typically around 0.17 mm for a standard coverslip.

Read the Edited Video Transcript for ‘BEST Pathology Microscope? Olympus BX41!’

Hey, this is Chad with Munday Scientific. Today, we’re going to talk about one of my favorite microscopes, the Olympus BX41.

This particular microscope is set up for pathology use, and the BX41 is one of the refurbished microscopes that goes out our door more than just about any other model we sell.

We’re going to take a closer look at the microscope, go over some of its features, and discuss some of the different options available.

Tilting Binocular Head

This BX41 is equipped with a tilting binocular head, which is probably the most common head we sell with this microscope.

It’s very ergonomic and can be tilted up or down to provide a more comfortable viewing position.

The microscope has Olympus WHN 10X/22 eyepieces, providing a 22 mm field of view.

If you’re a pathologist and need to make measurements, a reticle can be installed in the eyepiece. The eyepiece has a reticle shelf inside specifically for this purpose.

Reticles are often installed in a focusable eyepiece, allowing you to adjust the focus of the reticle independently and get a nice, sharp image.

Trinocular Head Option

Another option for the BX41 is a trinocular head, such as the Olympus U-TR30-2.

It installs in the same location as the tilting binocular head and can be secured using the microscope’s built-in 3 mm Allen wrench.

Whenever installing or removing a microscope head, always keep one hand on the head until you’re certain that it is securely tightened.

The trinocular head includes a pull rod that controls how the light is directed between the eyepieces and the camera port. Depending on the position of the rod, you can direct the light to the eyepieces, split the light between the eyepieces and camera, or direct the light to the camera.

This makes the trinocular configuration a good choice if you plan to add a microscope camera.

Nosepiece and Objectives

Moving down the microscope, this particular BX41 has a six-position nosepiece.

This version does not have a slot for an analyzer, although nosepieces with an analyzer slot are available. The BX41 will also commonly be found with a five-position nosepiece.

For this pathology configuration, we have:

• 2X objective
• 4X objective
• 10X objective
• 20X objective
• 40X objective

That’s a very common objective configuration for pathology.

There are also a wide variety of objective options available, including Plan, Plan Fluorite, and Plan Apo objectives, depending on your application and image-quality requirements.

Stage Options

This microscope has a mechanical stage with a slide holder.

If you prefer to move the slide manually with your fingers, the slide holder can be removed.

You can also configure the microscope with a stage that doesn’t have the coaxial stage controls. This keeps the controls out of the way for pathologists who prefer to manipulate their slides by hand.

Flip-Out Condenser

Underneath the stage, we have a flip-out condenser.

The reason we use this condenser on pathology microscopes is to properly fill the field when using low-magnification objectives such as the 2X or 1.25X.

Without the appropriate low-magnification condenser configuration, you may see vignetting or a shadow around the outside edge of the field when using the 2X objective.

Daylight Blue Filter

This BX41 uses a halogen illumination system, so you’ll also find a daylight blue filter in the illumination path.

If we remove that filter, you’ll notice that the halogen illumination has a warmer, more yellow appearance.

The daylight blue filter helps correct that warmer color temperature and produces a cooler, whiter appearance through the microscope.

Field Diaphragm and Light Control

The BX41 also has a field diaphragm and an adjustable light-intensity control.

There’s also a preset illumination feature. When the preset button is engaged, you’ll see the indicator illuminate.

Once you’ve determined the illumination level you prefer, the preset can be adjusted with a small flathead screwdriver. With the preset engaged, the illumination remains at that predetermined level.

This can be particularly useful in a laboratory with multiple microscope users because it allows you to establish a consistent illumination setting.

BX41 Lamp Housing

Another component worth discussing is the lamp housing.

The BX41 uses a 6V, 30W halogen bulb, and we have other videos demonstrating how to replace the bulb.

If you’ve recently installed a new bulb but the microscope still doesn’t illuminate—even though the microscope’s power indicator comes on—there’s a possibility that the lamp housing itself has failed and needs to be replaced.

These lamp housings are relatively inexpensive to replace and can help keep an older BX41 working for many more years.

Condenser Centering and Köhler Illumination

When reassembling the microscope, make sure the condenser is properly seated in the substage assembly.

You’ll also see two condenser-centering controls. These are used when setting Köhler illumination.

We have another video specifically demonstrating how to set Köhler illumination, and we’ll include a link to that video in the description.

Proper setup and alignment help ensure that the microscope performs as intended and that the objectives remain parfocal as you move from one magnification to another.

Handling the Nosepiece and Objectives

One important tip when removing or installing the nosepiece is to lower the stage first.

The nosepiece and objectives can be heavier than you might expect, so support the assembly securely. It’s always a good idea to use two hands whenever possible.

I’ve done this a lot, but I still make sure everything is supported until I know it’s securely locked in place.

Why We Like the Olympus BX41

That’s basically the Olympus BX41.

I really like this microscope. It has a strong, heavy-duty aluminum frame, and these microscopes have stood the test of time. Many of them are now 15 to 20 years old and are still excellent instruments.

You can also upgrade a BX41 to LED illumination, which can give an older microscope a much more modern illumination system.

For a pathology configuration like this one, you’re looking at a refurbished microscope in the neighborhood of $5,000, depending on the exact configuration and options.

It’s a great choice for a new lab, dermatopathology, home pathology applications, clinical laboratory work, hospital use, or anyone looking to upgrade their existing microscope.

Read the Edited Video Transcript for ‘Parfocal a Unitron Z645 Stereo Microscope’

Hey, this is Chad with Munday Scientific. Today, we’re going to show you how to parfocal the zoom on a stereo microscope.

For this example, we’re using a Unitron Z645 stereo microscope, along with one of our Unitron cameras and a tablet display so you can easily see what we’re doing.

Start at the Lowest Magnification

We’ve intentionally started with the microscope out of focus.

Begin by setting the stereo microscope to its lowest magnification. With the microscope at the low end of its zoom range, use the main focus control to bring your specimen into focus.

Zoom to the Highest Magnification

Once the specimen is focused at the lowest magnification, zoom the microscope all the way in to its highest magnification.

At the highest magnification, bring the specimen back into sharp focus.

We’re using the tablet and camera for this demonstration so you can clearly see the focusing process.

Return to the Lowest Magnification

Once you have achieved sharp focus at the highest magnification, zoom the microscope back out to the lowest magnification.

At this point, if you’re working directly through the eyepieces rather than using a camera, you’ll use the diopter adjustments on the eyepieces to fine-tune the focus.

Adjust the Eyepiece Diopters

Look through the microscope and adjust each eyepiece’s diopter individually until the specimen is in sharp focus.

Perform this adjustment for both eyepieces.

The important point is that once you’ve established focus using the microscope’s main focus control at the high end of the zoom range, use the eyepiece diopters to make the necessary correction at the low end.

Check the Parfocality

Once both eyepieces have been properly adjusted, test the microscope by slowly zooming from the lowest magnification to the highest magnification and then back again.

The specimen should remain in focus throughout the entire zoom range without requiring significant adjustment of the microscope’s main focus control.

Looking through this particular Unitron Z645, we can see that the specimen holds focus throughout the entire zoom range.

The microscope is now properly parfocal.

About the Unitron Z645

The Unitron Z645 is an excellent stereo microscope that can be used for a wide variety of inspection applications, including:

• Coin inspection
• Jewelry inspection
• Entomology
• Industrial inspection
• General laboratory and inspection work

Its zoom range makes it particularly useful for applications where you need to move between lower and higher magnifications while maintaining a clear view of the specimen.
