Problems It Solves
- A trinocular Olympus microscope without a C-Mount adapter cannot accept standard digital cameras
- Mismatched lens reduction ratios cause vignetting or partial sensor coverage
- Non-parfocal adapters force refocusing when switching objectives, slowing inspection
- Poor optical coupling leads to uneven illumination and edge light loss
- Using a generic adapter risks misalignment and image degradation due to non-telecentric design

- Built-in reduction lenses: 1X, 0.63X, 0.5X, 0.35X
- Telecentric optical design minimizes light fall-off at the sensor edges
- Diffraction-limited MTF ensures high resolution across the full field
- Aperture fully coupled with the objective's exit pupil for consistent exposure
- Parfocal with all UIS microscope objectives, maintaining focus across magnification changes
- Designed for Olympus BX, BX2, CX, CX2, MX, STM, SZX, IX, GX (GX41) series microscopes
- Anodized aluminum body resists corrosion and maintains dimensional stability

Comparison With Other Options
| Generic C-Mount adapter without reduction lens | This adapter includes built-in reduction lenses to match sensor sizes, avoiding vignetting and ensuring full field coverage |
|---|---|
| M42-Mount adapter (U-TV1.2XT2) | This adapter uses C-Mount (25.4mm, 32 TPI); M42-Mount is for different camera systems and is not interchangeable |
| Direct C-mount attachment to Olympus phototube | A direct fit is not possible due to diameter mismatch; this adapter provides the correct 35mm to 25.4mm transition with optical correction |
Use Guide
- Verify the Olympus microscope model is in the supported list (BX, CX, MX, etc.) before installation
- Align the adapter with the trinocular phototube and screw in gently until secure
- Select the reduction lens (1X, 0.63X, 0.5X, 0.35X) based on the sensor size of your camera
- Attach the C-Mount camera and ensure the threads are fully engaged
- Check focus and field of view; adjust camera position if needed to avoid vignetting
- Use only with UIS-compatible objectives to maintain parfocality

Frequently Asked Questions
Which Olympus microscopes are compatible with this adapter?
This adapter is designed for Olympus BX, BX2, CX, CX2, MX, STM, SZX, IX, and GX (GX41) series trinocular microscopes.
What sensor sizes does the adapter support?
It supports 1", 2/3", 1/1.8", 1/2", 1/2.5", 1/3", and 1/4" sensor chips, depending on the selected reduction lens.
Does the adapter require a separate power supply?
No. The adapter is passive and only provides mechanical and optical coupling; power is supplied by the camera.
Can I use this adapter with a non-Olympus microscope?
No. It is specifically designed for Olympus trinocular phototubes with a 35mm outer diameter.
Is the adapter parfocal with different objectives?
Yes. It is parfocal with all UIS microscope objectives, so focus remains stable when switching magnifications.
What is the difference between the 1X and 0.35X versions?
The 1X version matches 1" sensors directly; the 0.35X version reduces image size to fit smaller sensors like 1/4" or 1/3" without cropping.
