Flange focal distance
C-Mount
Flange focal distance is the optical distance from the mounting flange to image
sensor. Prosilica GX 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.
Adjusting the lens to infinity
Precondition: Use a C-Mount compatible lens that allows an infinity focus.
1.
Set the lens to infinity and image a distant object (10 to 15 m). Make sure the
lens is firmly threaded onto the C-Mount ring.
CS-Mount
Prosilica GX cameras are shipped with adjustable C-Mount. The camera can also
be built with a CS-Mount with a standard 12.50 mm optical flange focal distance
and a ± 10 µm tolerance.
