Install the C-Mount Lens and Cover (COV-7000-CMNT-LG)
Complete the following steps to install a C-Mount lens and cover to the vision system. The C-Mount cover (COV-7000-

A C-Mount lens has the following restrictions:

Maximum thread length is 5.25mm.

The C-Mount lens threads and body cannot protrude more than 6.5mm in length into the vision
system when screwed in, unless the diameter of the back lens is smaller than 19.25mm. If the C-
Mount lens threads and body protrude more than 6.5mm, you can add a spacer between the lens

maximum lens body diameter is 55mm and the maximum diameter including locking screws is 55mm.
