TeO2 Glan Polarizing Prism (glued)

The most popular prism for linear polarizing light.
Application – scientific & industrial fields where polarizing light is used.

  • Two prisms are connected with a glue with a specially selected refractive index.
  • Working is ordinary beam and extraordinary beam is absorbed by side surface.
  • Angular aperture two times larger than the prism air-clearance

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 GPGL-Vt – 370 – 460 nm basic wavelength is 405 nm α = 8,00º (for this wavelength α max and symmetrical)

Type GPGL-Vis– 440 – 750 nm basic wavelength is 514 nm α = 7,69º (for this wavelength α max and symmetrical)

Type GPGL-NIR– 600 – 1800 nm basic wavelength is 800 nm α = 7,47º (for this wavelength α max and symmetrical)

Type GPGL-MIR– 1000 – 5000 nm basic wavelength is 1330 nm α = 7,40º (for this wavelength α max and symmetrical)
