Wenglor ZVZG202, Polarization Filter for C mount lens

Linear polarization filters (also called rotating polarization filters) are used to eliminate or greatly reduce reflections. By rotating the frame and visually observing the result, you can determine the position where the glare effects are lowest. The locking screw ensures that the filter remains optimally positioned in the event of vibrations or accidental movements during cleaning. Polarization filters for external illumination must be ordered separately.
