TeO2 Wollaston Polarizing Prism

Prism separates the incident beam into two linearly polarized beams with orthogonal polarizing orientation.

Application – phase-contrast microscopes, interferometers etc.

  • Two prisms where optic axes are mutually perpendicular are cemented together.
  • Light propagation direction doesn’t coincide with optic axis in no one prism half that completely excludes parasitic effect of crystals optical activity.

We offer two prism types:

Type WPP5 – beam displace θ=5 degrees for 633 nm with ration of length to the aperture L/A=0,5-1

Type WPP10 – beam displace θ=10 degrees for 633 nm with ration of length to the aperture L/A=0,8-1,2
