Efficiently separates the s- and p- polarization components   Optimised for popular laser wavelengths   Brewster Thin Film polarizers with dimensions up to 200x150 mm are available   Standard Brewster Thin Film Polarizers available from stock

Brewster Thin Film polarizers are used for high energy applications. They have high damage threshold reaching 10 J/cm² @ 1064 nm 8 ns. Brewster polarizers are used as an alternative to Glan- Taylor laser polarizing prisms or cube polarizing beamsplitters. Typically, BK7 or UVFS dielectric coated Brewster Thin film polarizers separate the s- and p-polarization components of high energy laser beams and are intended for intra and extra cavity usage. Typical polarization ratio T_p/T_s is 200:1 and it is achieved at 56° AOI (Brewster angle). For optimal transmission Brewster Thin Film Polarizer should be mounted in an appropriate holder for angular adjustment.
