Glan Laser Polarizers

Glan Laser polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allows the rejected beam to escape out of the polarizer,which makes it more desirable for high energy lasers. Glan-Laser Polarizers offer a high extinction ratio with the added feature that both the extraordinary rays and ordinary rays are accessible.



Features:

Air-spaced 
Close to Brewster's Angle Cutting. 
High Polarization Purity. 
Short Length. 
Suitable for low to medium power application where the rejected beam is not required.
