Adjustment of C-Mount
The C-Mount or CS-Mount is adjusted at the factory and should not require
adjusting. If for some reason the lens mount requires adjustment, use the fol-
lowing 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 (CS-Mount compatible lens, if using CS ring)
that allows an infinity focus. Set the lens to infinity and image a distant object—
10 to 15 m should suffice. Make sure the lens is firmly threaded onto the C-
Mount ring. Rotate the lens and C-Mount ring until the image is focused. Care-
fully tighten the locking ring and recheck focus.
