BEST Pathology Microscope? Olympus BX41 Breakdown

Read the Edited Video Transcript for the Pathology Microscope BX41 Breakdown

Hey, this is Chad with Monday Scientific. Today, we’re going to talk about my favorite scope: and perform a pathology microscope BX41 breakdown.

This microscope is set up specifically for pathology use, and it’s by far the most popular refurbished scope we sell. It goes out the door more than any other model we carry.

We’re going to walk through some of the key features and options available on this scope.

Head Configuration

This model has the tilting head, which is the most common head we sell with the BX41. It’s ergonomic, tilting up and down, and comes with WHN 10x/22mm field-of-view eyepieces.

If you’re a pathologist who needs to take measurements, you’ll appreciate that one eyepiece is reticle-ready with a reticle shelf. Just screw in a reticle, and if you’re using a focusable eyepiece, you can sharpen the reticle for a clear view.

Trinocular Head Option (continued pathology microscope BX41 breakdown)

Next, we’ll take off the tilting head and show you the trinocular head (U-TR30-2).

It installs just like the tilting head. Always keep your hand on the head until it’s fully secured with a 3mm Allen wrench. This head features a pull/push rod that splits the light path between the camera and the eyepieces:

• Halfway out: splits light to both.
• Fully out: 100% light to the camera.
• Fully in: 100% light to the eyepieces.

Nosepiece

Now we’ll drop the stage and take a look at the nosepiece.

This one features a six-position nosepiece (some come with five). It doesn’t have a slot for an analyzer, but that’s an option. The objectives installed here are:

• 2x
• 4x
• 10x
• 20x
• 40x

This is the most common setup for pathology. You can also choose from Plan, Plan Fluorite, or Plan Apo objectives depending on your needs.

Stage & Slide Holder

The slide holder is removable if you prefer to move slides manually. You can also add a lock stage without coax controls to keep it out of your way.

Condenser & Filters (continued pathology microscope BX41 breakdown)

This scope includes a flip-out condenser (U-SC3), ideal for low magnification (1.25x and 2x). Without it, you’ll see vignetting or shadowing around the edges.

Removing the condenser shows the substage bracket, and this scope includes both a daylight blue filter and a didymium filter, which are especially helpful since the light source is halogen.

When the filters are removed, you’ll notice a warmer yellow hue from the halogen bulb.

Lighting Controls

The scope features:

• Field diaphragm
• Light intensity control
• Preset light button: When activated, the light level locks in place (indicated by a green light). This is great for multi-user environments. You can fine-tune it with a flathead screwdriver.

Lamp House

One last thing—let’s talk about the lamp house.

This scope uses a 6V 30W halogen bulb, which typically costs around $54–$60. If your bulb is new but the scope still won’t light up (and the power switch illuminates), there’s a good chance the lamp house needs replacing—usually every 10 years or so.

Final Thoughts

After completing this pathology microscope BX41 breakdown, let’s reassemble the scope—starting with the substage. You’ll notice a small stage pin that clicks into place. These two knobs on the substage are for centering the condenser.

We have another video linked in the description on how to set Köhler illumination, which helps ensure the scope is parfocal from one objective to the next—within a quarter turn, which is factory spec.

Pro tip: Always lower the stage and use two hands when swapping objectives or nosepieces. I’ve done it a million times, but it’s still the safest way.

Now we’ll lock the head back on, and that’s it—that’s the Olympus BX41.

I absolutely love this scope. It has a solid aluminum frame, is incredibly durable, and even though many of these are 15–20 years old, they still perform like champs. You can even upgrade to LED illumination to make it feel brand new.

These are typically priced around $5,000 in this configuration—perfect for new MOHS labs, derm/path, home pathology, or clinical settings. I’d put this scope up against anything out there for clinical use.
