Thin Film Polarizer plate

详情

Brewster type thin film polarizers are used for energy laser applications.
They have high damage threshold reaching */*@********************rewster polarizers are used as an alternative to Glan-Taylor laser polaring prisms or polarizing beamsplitters cube.
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 **0:1 and is achieved at *6°AOI(Brewster angle). For optimal transmission Brewster type thin film polarizer should be mounted in an appropriate holder for angular adjustment.
LASERTEC use our super polished substrates and IBS coating to supply a series of high extinction ratio, thin film polarizers.The wavelength range from UV to NIR. With our precision polishing technology and Ion Beam Sputtering deposition technology,The customized Polarizer upto ***0:1 with Tp>*8%
