5.1.4 C-Mount Speciﬁcations

The Flange Back Length of the CS-Mount is 12.5mm versus 17.526 of the C-Mount. The shorter Flange

Back Length of the “CS-Mount” allows room for the stripe ﬁlter incorporated in the color camera.

Additionally, the shorter Flange Back Length allows for reduction of the effective diameter of the ﬁrst

lens and reduces the number of lens elements. The common C-Mount lens is completely compatible

with a CS-Mount camera when a 5mm extension ring is inserted between the lens and the camera.
