Brewster Thin Film Polariser, for Yb doped material, 343nm

Manufacturer's part number :


Manufacturer Altechna


Description :

Brewster Type Thin Film Polarizers for Yb doped material 343 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.
