BAD KREUZNACH - 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.
These 1 mm thin filters are provided with an ultra-low reflection coating, important for e.g. traffic surveillance. The wavelength tolerance of only +/- 1 % makes them a preferred choice for metrology systems. Optimized for common LEDs used in machine vision, the filters are ideal for automated inspection systems as food & beverage control or logistics. For example, the blue BP 465-70 HT bandpass is often used in 3D measurement applications. For night/day vision cameras Schneider-Kreuznach offers the VIS-85 type, transmitting in visible 430-680 nm and 855 nm +/- 15 nm.
