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 17:). Table 13 presents lens protrusion values for
Prosilica GE cameras with C-Mount.
