Discover The 1 mm Optical Filters From Schneider-Kreuznach
5/7/2020
Filters play an important part in an imaging system. They block unwanted wavelengths and troublesome surrounding light, while selected wavelength ranges are transmitted at a high percentage. As an optical element the filter must fulfill some requirements to ensure that it has no impact on the resolution of the complete system. The quarter wave wavefront distortion also ensures that the MTF is not affected. Our 1 mm thin filters with a high surface quality are developed to be placed between lens and sensor. Equipped with the Schneider-Kreuznach typical coating with high transmission and steep slopes, they are the ideal choice for challenging machine vision applications.
