C-Mount

A

C-Mount

is a type of lens mount commonly found on 16mm movie cameras, closed-circuit television

cameras (CCTV), trinocular microscope photo tubes and CCD/CMOS digital cameras. C-Mount lenses
provide a male thread which mates with a female thread on the camera. The thread is nominally 25.4mm
[1"] in diameter, with 32 threads per inch, designated as ”1-32 UN 2A” in the ANSI B1.1 standard for unified
screw threads. The flange focal distance is 17.526mm [0.69"] and thread length 3.8mm [0.15"].
