Disassemble & Assemble an Olympus Microscope Dualhead Bridge
Read the Edited Video Transcript for ‘Disassemble & Assemble an Olympus Microscope Dualhead Bridge’
Hey, this is Chad with Munday Scientific. Today, I’m going to show you how to disassemble and reassemble a multi-headed Olympus BX microscope.
These systems are commonly used for:
- Teaching
- Multi-user viewing
- Pathology consultation
- Training applications
We’ll walk through the process step by step, including proper setup after reassembly.
Tools Needed
For most Olympus BX microscopes, you’ll need a 3 mm Allen wrench.
Options:
- Use the built-in Allen wrench if your microscope includes one
- Or use a standard Allen key set
Step 1: Remove the Viewing Heads
To begin:
- Locate the screw holes on each side of the heads
- Tilt each head backward before removal
⚠️ Important:
Tilting the heads back helps prevent the eyepieces from falling out.
Removal Process:
- Loosen the retaining screws
- Carefully remove each head
- Set them aside safely
Step 2: Remove the Bridge Assembly
Once the heads are removed, move to the bridge assembly.
Removal Steps:
- Locate the collar
- Rotate the collar until it loosens
- Slide the bridge assembly off
Step 3: Remove the Post
The post is typically secured with a black dovetail screw.
Steps:
- Loosen the dovetail screw
- Remove the post
Step 4: Disconnect Pointer or Power Supply
Depending on your microscope model:
BX40:
- Pointer or accessory power may plug into the back
Newer LED Models:
- LED pointer power supply may plug into the side
⚠️ Always unplug power before disassembly.
Step 5: Remove the Splitter
Using your Allen wrench:
- Loosen the splitter from the dovetail
- Remove it carefully
At this point, the microscope is fully disassembled.
Reassembly Overview
Now we’ll put everything back together.
Step 1: Reinstall the Splitter
- Position the splitter onto the dovetail
- Hold it securely with one hand
- Tighten it with the Allen wrench
Important:
Once tightened, gently wiggle it to confirm there is no movement.
Step 2: Reinstall the Post
Chad recommends installing the post onto the stand first, as it’s generally easier.
Steps:
- Screw the post onto the stand
- Tighten securely
Step 3: Reinstall the Bridge Assembly
- Slide the bridge flange into position
- Rotate the collar to tighten
⚠️ Important:
Hold the bridge while tightening, as gravity can pull it downward.
Once positioned:
- Adjust height as needed
- Tighten the post lock
Pro Tip:
Use a level to ensure the bridge is perfectly horizontal.
Step 4: Reinstall the Heads
For each head:
- Position it on the flange
- Keep one hand on the head
- Tighten with the Allen wrench using your other hand
Safety Tip:
Always wiggle the head after tightening to confirm it is secure.
Repeat for the second head.
Step 5: Set Up Color Illumination
After assembly, proper Köhler/color illumination is critical.
Recommended Process:
- Set up illumination on the driver side
- Check the passenger side
- Slowly expand the field diaphragm
- Ensure both sides:
- Are centered
- Reach the edges evenly
- Appear visually similar
This ensures both users are seeing the same properly aligned image.
Eyepiece Configuration
Multi-head systems typically use different eyepiece configurations for the driver and passenger sides.
Driver Side:
- Usually fixed eyepieces
Passenger Side:
- One fixed eyepiece
- One focusable eyepiece (diopter side)
This allows the passenger to adjust focus to match what the primary viewer sees.
Final Thoughts
A properly assembled multi-headed Olympus BX microscope provides:
- Excellent teaching capability
- Reliable shared viewing
- Consistent image quality across both heads
Taking time to align the bridge and set illumination correctly is essential for the best user experience.
