Glan-Laser-Polarizers

  • Air-spaced
  • High polarization purity, short length
  • Suitable for medium to high power applications

Glan Laser prism polarizers are made of two birefringent prisms of the same material 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. This polarizer with two escape windows allows the rejected beam to escape out of the polarizer, which makes it more desirable for high power lasers.

The length to aperture ratio of the Glan Laser polarizer is less than 1.0 makes it a relatively thin polarizer. This polarizer with side escape windows is suitable for medium to high power applications.

As with all of our optics, we will gladly provide these items custom designed to your particular requirements. As an alternative, we offer a selection of standard items as specified below.
