Brewster Windows are primarily used in laser cavities to produce a beam with a high degree of polarization purity. When unpolarized light is incident on an uncoated substrate at Brewster’s Angle, the reflected portion is completely S polarized and the transmitted portion is partially P polarized.
Muliple passes through the substrate Substantially reduces the S component in the transmitted beam, resulting in a highly P polarized output. multi-layer thin Film Polarizer coatings can be applied to these substrates to greatly improve efficiency and extinction ratio on a single pass through the substrate.
TO ORDER : Use substrate codes to order uncoated Brewster Windows. Refer to the THIN FILM COATING
section for information on Thin Film Polarizer coatings that can be applied to these substrates.
Please contact our sales department fo assistance with specifying coatings and part numbers.
Other substrate materials and specifications can be provided upon request.
