Prosilica GC Technical Manual V2.2.0
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.
Image to infinity
Use a C-Mount compatible lens that allows an infinity focus. Set the lens to infinity
and image a distant object (10 m to 15 m). Make sure the lens is firmly threaded
onto the C-Mount ring. Rotate the lens and C-Mount ring until the image is
focused. Carefully tighten the locking ring and recheck focus.
