Camera dimensions
Optical flange focal distance
Optical flange focal distance is the optical distance from the mounting flange to
the image sensor die (see figure 24 and figure 25). Optical flange focal distance
can be calculated as:
C-Mount cross section
Table 13 presents flange focal distance and maximum lens protrusion values for
Prosilica GE cameras with C-Mount.
