Knowledge of microscope interface

What is a C / CS interface?
The origin of the word "C" is the initial letter of "cinema", and the origin of the C interface is the camera lens. At present, the C interface is made up of standard interfaces from 16mm cameras, TV cameras, and trinocular microscopes. The C mount lens provides a male thread to match the camera's female port. The diameter of the thread is 1 inch (25 mm), 32 threads per inch, designed according to the "ANSI B1.1" standard.
* The focal plane distance of the C interface is 17.526 mm.
* The CS interface is the focal plane distance 12.52 mm, and the remaining parameters are the same as the C interface (C-Mount Adapter).
Therefore, a "C / CS 5mm adapter" can be used to convert "C-mount lens" to "CS mount"
The simple distinction between the C interface and the CS interface of the lens is based on the lens installation classification. All camera lenses are threaded. There are two industry standards for the lens installation of CCD (CCD Microscope Camera) cameras, namely C mount and CS installation. seat. Both thread parts are the same, but the distance between the two from the lens to the photosensitive surface is different. The two main lens mounting standards are C-mount and CS-mount. They all have a 1 inch long thread and look very similar. Their difference lies in the distance between the lens and the sensor after the lens is mounted on the camera:
CS-mount: The distance between the image sensor and the lens should be 12.5 mm
C-mount: The distance between the image sensor and the lens should be 17.5 mm. A 5 mm washer (C / CS connecting ring) can be used to convert a C-mount lens to a CS-mount lens
C-mount is the original standard, and CS-mount is an upgrade to it, which can reduce manufacturing costs and reduce sensor size. Most cameras and lenses on the market today use the CS-mount standard. An old C-mount lens can be mounted on a camera with a CS-mount interface by using a C / CS connection ring. If the camera cannot focus, it may be because the wrong lens type is used.
