The Glan Laser Calcite Polarizer is manufactured from select portions of the calcite crystal, making it an appropriate choice for high energy laser applications. They provide extremely pure linear polarization (100,000:1). Two polished side ports are provided to allow bi-directional use of the polarizer. The input and output faces are polished to a laser quality 20-10 scratch-dig surface finish to minimize scattering of the transmitted P polarization component of the laser beam or light field. The S polarization component is reflected through a 68^o angle and exits the polarizer through one of the two side ports, which are pad polished.

Glan Laser Polarizer, 15 mm CA, Coating: 600-900 nm (High Power Apps.)

The Glan Laser cvalcite polarizer is a Glan Taylor polarizer that is specially designed to deal with high energy laser light. These polarizers are manufactured from only the select portions of the calcite crystal that pass a sensitivity laser scattering test. Two polished side exit ports are provided to allow bi-directional use of the prisim polarizer. These side ports also ensure that the rejected light from high power lasers can be safely removed from the polarizer.
