TeO2 Glan Polarizing Prism (air spaced)

 

The most popular prism for linear polarizing light.

Application - scientific & industrial fields where polarizing light is used.

 

- Two prisms are connected with a small air-clearance.

- Working is ordinary beam and extraordinary beam is absorbed by side surface.

- The smallest polarizing non-uniformity on all aperture

Type GPAS-Vis  - 440 - 750 nm basic wavelength is 532 nm α = 4,25º (for this wavelength α max and symmetrical)

Type GPAS-NIR  - 600 - 1800 nm basic wavelength is 800 nm α = 4,07º (for this wavelength α max and symmetrical)

Type GPAS-MIR  - 1000 - 5000 nm basic wavelength is 1330 nm α = 4,00º (for this wavelength α max and symmetrical)
