All about C-mount lenses
In order to connect a lens to a camera, we need a threaded connection—the mount. Mount sizes are standardized and are indicated by letters, with the C-mount being the most common type used for machine vision cameras. It is used for sensor diagonals measuring up to 20 mm, or 1.5 inches. The thread has a nominal diameter of 1 inch (24.5 mm) and a pitch of 1/32 inches. The flange focal distance of this lens mount is 17.526 mm (0.69 inch).

Adapter rings expand application areas
Adapter rings can allow you to connect C-mount lenses to CS-mount cameras, broadening the application reach of the equipment. Note that CS-mount lenses cannot be connected to C-mount cameras due to the shorter flange focal distance.
