Schneider Polarizers

Natural light and most light sources emit unpolarized light. Polarizers are an excellent solution in applications that require glare reduction due to reflected light. They are also used in several optical instruments.

Unpolarized light passing a linear polarizing filter will be linear polarized afterwards in the orientation of the polarizing axis of the filter. A circular polarizer is a combination of a linear polarizer and a quarter wave retarder. Crossing the axes (or left handed with right handed, when using circular) blocks nearly all light. Circular polarizers are recommended if optics as mirrors are within the optical path from filter to sensor.

Schneider Kreuznach polarizers are designed to fulfill industrial requirements. They are made of dichroic laminated polarizing polymers cemented between 2 slides of protective glass. Polarizers are sensitive to humidity, therefore we recommend our unmounted filters as edge sealed version.

Linear and circular polarizers are available as glass filters, unmounted in sizes 10 mm to 74.0 mm diameter and mounted with common thread sizes M 25.5 to M 67 or as film up to 420 x 1270 mm size and 0.3 or 0.8 mm thick. Custom sizes on request.
