Optical flange focal distance
Optical flange focal distance is the optical distance from the mounting flange to
image sensor die (see figure 38 and figure 39). Optical flange focal distance can
be calculated as:
C-Mount cross section
Table 21 presents flange focal distance and maximum lens protrusion values for
Prosilica GT cameras with C-Mount.
