Brewster Thin Film polarizers are used for high energy applications.
They have high damage threshold reaching 10 J/cm² @ 1064 nm for 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 Type 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 Tp/Ts is 200:1 and it is achieved at 56 ° AOI (Brewster angle). For optimal transmission Brewster Type Thin Film Polarizer should be mounted in an appropriate holder for angular adjustment.
Dual band or other dimensions thin film polarizers are available by
request.
