Brewster Thin Film Polariser, for Ti:Sapphire, 400nm

Manufacturer's part number :


Manufacturer Altechna


Description :

Brewster Type Thin Film Polarizers for Ti:Sapphire 400 nm 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 achieved at 56 deg angle with minimal losses. For optimal transmission Brewster Type Thin Film Polarizers should be mounted in appropriate holder for angular adjustment.
