5. Every brand is unique. A microscope is like a car. You cannot take a part from Toyota and put into BMW. Microscope manufacturers use different size of video port (to sell more!).

BIOIMAGER offers various SLR and C-Mount adapters for digital microscopy cameras to use with all brands of microscopes, e.g. Carl Zeiss, Olympus, Nikon, Leica, Meiji Techno, Leitz, Wild, Huvitz etc. A microscope c-mount adapter is used to connect a microscope main body (trinocular head or video port) to a camera to the microscope trinocular port. A C-mount or CS-mount adapter has an external standard 1″-32 or 25.4mm diameter.

4. You can increase the magnification optically in a screen (besides digital zooming) using a high-magnification lens of c-mount adapter rather than a standard one. For instance, if your camera has a 1/3” chip (or sensor), you need a 0.35x c-mount adapter to generate the image at the resolution of a 10x eyepiece. Using a 0.66x or 1x c-mount adapter, you can expect the image is magnified twice or tripled, i.e. an image at the size of 20x or 30x eyepieces can be seen in your computer screen. The only drawback here is you will have a smaller field of view as this happens by moving from 20x objective lens to 40x or 60x, accordingly.

B) Field of Views of a camera with different C-mount adapters with BUM500 upright microscope at 40x objective lens. The high magnification c-mount adapters give smaller field of view but higher resolution.

6. There is a T-mount adapter beside C-mount adapter. The difference is simply the port size that goes to a camera. A T-mount has M42-75 thread. cameras with a sensor larger than 1″ normally uses T-Mount. Accordingly they need a 1x, 1.2x, 1.5x, or 2.25x T-Mount adapter. That you can use a C-Mount to T-Mount converter, it is a possibility to use an existing camera or adapter.

C-Mount adapter is an external part of microscope that allows you to connect a digital camera to your microscope through trinocular head or photo/video port (side port, front or back port depending on the microscope type and design). A C-mount adapter has two ends, one end of that connect to a digital microscopy camera which is normally a standard threaded port of 1″ (25.4mm) and another end of that connects to the video port of the microscope. Being said this as a mechanical specification, a c-mount adapter does one optical job. It projects the image, seen in eyepieces, into the camera sensor. The size of image seen through the camera on a screen at 100% scale (neither zoomed in nor zoomed out), should match with the size of image seen by a 10x eyepiece.
