Glan Laser Polarizer, a modification of Glan taylor polarizer

June 2, 2021

Glan Laser polarizer is made of two same birefringent material prisms that are assembled with an air space. Photonchina’s 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 allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratch dig surface quality specifications are assigned to these faces.
