TM-250 Miniature CCD Camera

7.1.3 C-Mount Speciﬁcations

FIGURE 21. Combination With “CS-Mount” Camera

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.
