Thin Film Polarizing Plate Beamsplitter (HPPB)
- Brewster angle polarizers
- 200 : 1 extinction ratio
- High power use
These plate polarizers are intended for use at the Brewster angle of incidence. The natural polarization which takes place at this angle is enhanced by the deposition of a coating to separate the s and p peak transmittance. They provide a high extinction ratio of 200: 1 and are suitable for high power use.
