Glan Laser Polarizer

Glan Laser Polarizer


Glan Laser Polarizer is designed specifically for high energy laser. It is made of two same birefringence material prisms that are assembled with an air space. The polarizer with two escape windows allows the rejected beam to escape out of the polarizer which makes it suitable for high power laser.

Features

Air-spaced
Close to Brewster's Angle Cutting.
High Polarization Purity.
Short Length.
Suitable for the High Power Application.
