C-Mount and CS Mount Lenses

Applications include ID CAMERAS, MACHINE VISION,  HD SURVEILLENCE, ROBOTICS,BIOMETRIC  LIFE SCIENCES… any OEM application that uses a C-Mount camera. The focus and iris can be locked in position.
F/0.95 apertures are available on the 17mm and 25mm C-Mount lenses.  If an iris and focus are not needed, lenses can be mounted into a plain barrel. They can also be treated to better meet harsh conditions including water and vibration—we are very experienced in putting elements in place to meet difficult vibration requirements.
We offer C-mount lenses for up to 10 MP sensors. Coverage is up to 1” format (16mm diagonal) sensors.


Westech is also an authorized ™Computar Dealer. Call us for fast delivery and competitive prices.
