Adjusting the C-mount
THE C-MOUNT IS ADJUSTED AT THE FACTORY AND SHOULD NOT
REQUIRE ADJUSTING.
If for some reason, the C-mount requires adjustment, use the following method.
Loosen Locking Ring
Use an adjustable wrench to loosen 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. A
wrench suitable for this procedure can be provided by AVT Canada Inc. (P/N 11-
0048A).
Image to Infinity
Use a c-mount compatible lens that allows an infinity focus. Set the lens to infinity and
image a distant object. The distance required will depend on the lens used but typically
30 to 50 feet 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. Carefully tighten
locking ring. Recheck focus.
