C-Mount Camera Microscope Adapter - Installation Guide

Typical connection methods for microscope C-mount camera adapters

This page is an information and instruction guide for selecting the correct physical connection method when installing a C-mount camera adapter on a microscope. The actual adapter parts required depend on the microscope model, phototube type and camera system.

Adapter Set Overview 2 pieces = 1 set

C-mount camera microscope adapter set with main body and 30 mm conversion sleeve

A C-mount microscope camera adapter set consists of the main adapter body and a 30.0 mm conversion sleeve. The main adapter can be inserted into a 23.2 mm eyepiece tube, while the conversion sleeve is used when adapting to a 30.0 mm eyepiece tube.

  • a. Main adapter body
  • b. Φ30.0 mm conversion sleeve
  • For trinocular phototube installation, an additional sleeve or microscope-side adapter may be required.

1-1. Φ23.2 mm Eyepiece Tube Installation

Insert the main adapter body directly into a standard 23.2 mm microscope eyepiece tube. This is one of the most common installation methods for C-mount microscope camera adapters.

1-2. Φ30.0 mm Eyepiece Tube Installation

For microscopes with a 30.0 mm eyepiece tube, use the Φ30.0 mm conversion sleeve with the main adapter body. Confirm the actual eyepiece tube diameter before installation.

2. Nikon F-type Phototube Installation

Some Nikon trinocular microscopes use an F-type phototube interface. In this case, a fixation sleeve or dedicated phototube sleeve may be required between the microscope-side phototube and the C-mount adapter system.

F-tube sleeve for Nikon F-type phototube installation F-Tube Sleeve NY-NF For Nikon F-type phototubes
JIS tube sleeve for JIS phototube installation JIS Tube Sleeve NY-JIS For JIS standard phototubes

The microscope-side phototube standard should be checked before selecting the sleeve. Similar-looking trinocular ports may require different adapters.

3. Olympus PT Phototube Installation PT Phototube Sleeve required

For Olympus PT-type phototubes such as SZ-PT, SZH-PT, U-SPT and IX-PT, use the compatible PT phototube sleeve as part of the adapter configuration.

If the trinocular port has only a plastic cap and no phototube installed, microscope-side components such as Olympus U-TV1X-2 and U-CMAD3 may be required before attaching a C-mount adapter.

4. Older Olympus BH-type Installation BH-type sleeve required

Older Olympus BH-type and related trinocular phototube configurations may require the NY-BH or another compatible sleeve. The correct part depends on the actual microscope-side phototube shape.

5. JIS Phototube Installation JIS Phototube Sleeve required

For microscopes equipped with a JIS phototube, use a JIS phototube sleeve such as NY-JIS to connect the camera adapter properly.

Before Selecting an Adapter

Please check the microscope model, trinocular tube type, eyepiece tube diameter, camera sensor size and required field of view. These details determine whether the installation can be made directly or whether an additional sleeve or microscope-side adapter is required.

Check item Why it matters
Microscope model and phototube type Different trinocular ports may require different sleeves even when they look similar.
Eyepiece tube diameter 23.2 mm and 30.0 mm tubes require different fitting methods.
Camera mount and sensor size C-mount camera selection affects magnification, field of view and image coverage.
