C-Mount flange focal distance
Flange focal distance is the optical distance from the mounting flange to image
sensor die. Prosilica GS C-Mount cameras are optically calibrated to a standard
17.526 mm optical flange focal distance, with a ±10 μm tolerance.
Adjustment of C-Mount
The C-Mount is adjusted at the factory and should not require adjusting. If for
some reason the lens mount requires adjustment, use the following method.
Loosen locking ring
Use an adjustable wrench to loosen the locking ring. Be careful not to scratch
the camera. When the locking ring is loose, unthread the ring a few turns from
the camera face.
