This polarizing filter reduces unwanted glare bouncing off many material types. With conventional lenses, filters are typically mounted at the object end of the lens. However, with telecentric lenses, the typical approach would be rather expensive because of the lens’s large diameter. This filter kit mounts the filter between the lens and the camera, thus keeping the filter small and the cost reasonable.

This filter kit is compatible with our C-mount Opto Engineering telecentrics designed for 1/2 and 2/3 size sensors, with exception of the TC23004, TC23007, TC23009, and TC23012. Incompatible with TC13xxx lenses for 1/3" sensor. Using the filter may cause some vignetting, depending on the size of the sensor. Since inserting the filter will increase the back focal length of the lens, a spacer (included in the kit) is used to tune the lens back to its nominal working distance.
