Polarizer Filter

Light reflected from a non-metallic surface becomes polarized, sometimes to the degree that a strong glare is created. A linear polarizer rotated to pass only light polarized in the direction perpendicular to the reflected light (the glare) will absorb much of it. Aside from reducing reflections, polarizers help to improve contrast by reducing dynamic range, allow for evaluation of stress in transparent plastic and glass, and can be used in pairs to form a variable neutral density filter.

Linear Polarizers

Recommended for minimizing glare in any application, passing light through a linear polarizer will also block approximately two-thirds of the incident light.

Circular Polarizers

A combination of a linear polarizer and a quarter wave retarder, circular polarizers are recommended for use in systems that employ a mirror or beamsplitter in conjunction with a light metering or auto-focus capability.

Visible Polarizers

Visible polarizers decrease glare over the 400-700nm wavelength range.

Near Infrared Polarizers

Near-infrared linear polarizers work best over the 700-1100nm wavelength range.
