Read the Edited Video Transcript for ‘BX51 Metallurgical DIC, Brightfield & Darkfield’

Hey, this is Chad with Munday Scientific and Microscope Marketplace. Today, we’re going to talk about an Olympus BX51 metallurgical microscope.

We typically focus on biological microscopes, but today we’re covering a materials (metallurgical) microscope. This particular unit has just been sold and is equipped with:

• Brightfield
• Darkfield
• DIC (Nomarski Differential Interference Contrast)

This setup is commonly used for applications such as silicon wafers and materials inspection, where enhanced contrast is critical.

Trinocular Head and Light Path Control

This microscope features a trinocular viewing head with standard light path options:

• All the way in: 100% of light to the eyepieces
• Middle position: Light split between eyepieces and camera
• All the way out: 100% of light to the camera

We have additional videos covering this in more detail, but today we’ll focus on contrast methods.

Reflected Light Illumination

This microscope uses reflected light illumination, meaning:

• The lamp house is located on top
• Light passes through the illuminator
• It reflects off a mirror and is directed down onto the specimen

This is ideal for opaque samples, such as metals or wafers.

In contrast, transmitted light systems shine light through the specimen from below.

Brightfield vs. Darkfield

The microscope includes a brightfield/darkfield selector lever.

• Brightfield: Standard illumination
• Darkfield: Enhanced contrast with a dark background

Switching between the two dramatically changes how the specimen appears.

Objectives and Nosepiece

This microscope uses Olympus Plan Fluor (FL) objectives designed for metallurgical work.

Objective Set

• 5×
• 10×
• 20×
• 50×
• 100×

Each objective is labeled “BD”, meaning it supports both:

• Brightfield
• Darkfield

These are high-quality objectives, commonly used in materials science applications.

DIC Prism Selection

The microscope includes a DIC slider system.

You’ll see markings such as:

• U Plan FL (current configuration)
• LM Plan (long working distance objectives)

For this setup:

• The U Plan FL setting must be engaged
• If using LM objectives, the slider position would need to be changed

Setting Up DIC (Differential Interference Contrast)

To achieve proper DIC imaging, several components must be correctly aligned.

Step 1: Bring Specimen into Focus

Focus the specimen using brightfield first.

Step 2: Insert Analyzer and Polarizer

Both the analyzer and polarizer must be engaged.

At this point, the image may not change significantly.

Achieving Extinction

Next, rotate the analyzer.

• As you rotate it, the image will become darker
• When the field becomes completely dark, you have reached extinction

This means:

• The polarizer and analyzer are crossed
• Their optical axes are aligned properly

This step is critical—DIC will not work without extinction.

Engaging the DIC Prism

Once extinction is achieved:

1. Insert the DIC prism slider
2. The image will now appear more three-dimensional
3. Contrast and color effects will become visible

Adjusting DIC Contrast

You can fine-tune the DIC effect by:

• Rotating the prism adjustment knob

This changes:

• Contrast
• Color interference patterns
• Apparent depth (3D effect)

Important Notes for DIC Operation

For proper DIC imaging:

• The polarizer must be in
• The analyzer must be in
• The poles must be crossed (extinction achieved)
• The correct DIC prism must match the objective
• The illumination must be properly aligned

If any of these are incorrect, the image will not display proper DIC contrast.

Demonstrating the Effect

If you remove either:

• The polarizer, or
• The analyzer

The DIC effect disappears, and the image will look completely different.

This highlights how important proper alignment is.

Final Thoughts

The Olympus BX51 with DIC is a powerful tool for materials analysis.

It allows users to:

• Enhance contrast dramatically
• Visualize surface features
• Achieve a pseudo-3D effect on flat samples

This makes it especially valuable for wafer inspection and industrial applications.

Read the Edited Video Transcript for ‘Olympus BX51 Phase Contrast Explained Simply’

Hey, this is Chad with Munday Scientific and Microscope Marketplace. Today, we’re going to talk about an Olympus BX51 microscope equipped with phase contrast.

This particular system was customized to meet a customer’s specifications, and we’re going to walk through the setup and explain how phase contrast works on this microscope.

Trinocular Head and Light Path Control

This microscope includes a trinocular viewing head with three light path positions:

• All the way in: 100% of light to the eyepieces
• Middle position: Light split between eyepieces and camera
• All the way out: 100% of light to the camera

Most users prefer the middle (50/50) position for simultaneous viewing.

Eyepieces and Diopter Adjustment

The microscope is equipped with two 10× eyepieces.

• The left eyepiece includes a diopter adjustment
• Start by aligning the zero mark with the white dot
• This is the baseline for 20/20 vision
• Adjust from there to match your eyesight

Objective Turret Removal

To access the objective turret:

1. Always lower the stage first
2. Use the 3 mm Allen wrench located on top
3. Loosen the screw slightly (about a quarter to half turn)
4. Slide the turret out from the dovetail mount

Objective Configuration

This microscope has a mixed configuration based on the customer’s needs:

• 4× objective: Brightfield
• 10× and 20× objectives: Phase contrast (green lettering)
• 40× objective: Phase contrast
• 100× objective: Brightfield (cost-effective option)

Identifying Phase Objectives

• Green lettering: Phase contrast objectives
• Black lettering: Brightfield objectives

Each phase objective is labeled with a PH designation:

• PH1 → Phase Ring 1
• PH2 → Phase Ring 2
• PH3 → Phase Ring 3 (if applicable)

Phase Contrast Condenser

The condenser includes multiple positions:

• 0 (Zero): Brightfield
• PH1: For 10× and 20× objectives
• PH2: For 40× objective
• Darkfield stop

To achieve phase contrast:

• The correct PH setting must be selected
• The objective must match the corresponding phase ring

How Phase Contrast Works

Phase contrast works by aligning:

• The phase ring in the condenser
• With the phase ring inside the objective

When properly aligned:

• The rings overlap
• This produces the phase contrast effect

If misaligned or mismatched:

• The image will appear dark, uneven, or distorted

Important Usage Tip

Phase objectives can still be used in brightfield mode without issue.

However:

• Using a brightfield objective with a phase ring engaged will result in a poor-quality image
• Expect dark spots, shading, and reduced clarity

Filters and Illumination

This microscope includes several filters:

• Green filter (custom-installed per customer request)
• Daylight blue filter
• Neutral density filters (ND)

Purpose of Filters

• Green filter: Enhances contrast for phase work
• Blue filter: Adjusts color temperature
• Neutral density filters: Reduce light intensity

Light Source and Brightness Control

The microscope uses a 12V 100W halogen light source.

• Controlled by a rheostat (brightness knob)
• High brightness is especially important for phase contrast imaging

Changing the Bulb

Always turn off and unplug the microscope before replacing the bulb.

Steps to Replace the Bulb

1. Insert the 3 mm Allen wrench into the access hole
2. Loosen the screw and pull out the lamp housing
3. Remove the top cover (secured with a 3 mm screw)
4. Locate the bulb
5. Press down the two brass clips
6. Remove the bulb
7. Insert a new 12V 100W bulb (avoid touching the glass)
8. Reassemble the housing and reinstall
