Introduction:
Glan-Laser Calcite Polarizer is made of 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 and 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-Deg angle and exits the polarizer through one of the two side ports, which are pad polished. Glan-Laser Polarizer is suitable for high power applications.
