Thin Film Plate Polarizer (TFP)
400
nm ≤ λ ≤ 2.0 µm
Thin Film Plate Polarizer coatings are applied to window substrates
and are primarily for use in laser cavities. Designed to operate at
Brewster’s angle, they efficiently separate an incident, unpolarized,
monochromatic beam into its S and P polarization components. The extinction
ratio (TP/TS) exceeds 200:1 in the transmitted beam. Coatings for high
power wavelengths use special materials that are able to withstand higher
power than standard thin film plate polarizer coatings. These all dielectric
coatings are sensitive to wavelength and angle of incidence.
