Glan Laser Polarizers
Description
A Glan–laser prism is a type of prism which is used as a polarizer or polarizing beam splitter. It is one of the most common types of modern polarizing prism.
The prism is made of two right-angled prisms of calcite(or a-BBO、YVO4) which are separated on their long faces with an air gap. These polarizers are typically designed to tolerate very high beam intensities, such those produced by a laser. Prisms with irradiance damage thresholds greater than 1GW/cm2 are commercially available.

Frequently Asked Questions
A Glan-laser prism is a type of prism used as a polarizer or polarizing beam splitter, made of two right-angled prisms of calcite (or a-BBO, YVO4) separated by an air gap.
Glan-laser polarizers are typically used in laser applications.
The wavelength range of Glan-laser polarizers varies depending on the material used, with calcite ranging from 350-2300nm and a-BBO ranging from 200-3500nm.
Glan-laser polarizers are designed to tolerate very high beam intensities, with commercially available prisms having irradiance damage thresholds greater than 1GW/cm2.
Glan-Taylor polarizers are available in both calcite and a-BBO materials, with a wavelength range of 350-2300nm for calcite and 200-1100nm for a-BBO. They have a surface quality of 20/10 and a beam deviation of less than 3 arc min. The housing is made of black anodized aluminum and they are available in various mounting sizes.
