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
Material TeO2
Extinction ratio <1:100000
Power capability 200 MWt/cm2
(1064nm, 12ns, 1Hz)
Surface quality S/D - 20/10
Flatness ¼ lambda (633nm)

We offer four prism types:

Type GPAS-Vt – 370 – 460 nm basic wavelength is 405 nm α = 4,55º (for this wavelength α max and symmetrical)

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)
