Camera dimensions
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 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. Carefully tighten the locking ring and recheck focus.
Lens protrusion for C-Mount cameras
Lens protrusion is the distance from outer edge of C-Mount ring to contact point
of first surface internal to C-Mount ring. For color cameras this surface is the IR-
filter holder, and for mono cameras this surface is the internal camera front
plate (see figure 25). Table 11 presents lens protrusion values for Prosilica GX
cameras with C-Mount.
