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 33). Table 18 presents lens protrusion values for Prosilica GC

cameras with C-Mount.
