Thin Film Polarizer

 Thin Film Polarizer separate the s- and p-polarization components. They are designed for use in high energy laser applications. Due to a high damage threshold, Thin Film Polarizer are used as an alternative to Glan Laser Polarizer or Polarizing Beam-splitter Cube.

LASERSTEC use our super polished substrates and IBS coating to supply a series TFP (thin film polarizer) of high extinction ratio. The wavelength range from UV to NIR. With our precision polishing technology and Ion Beam Sputtering deposition technology, The customized Polarizer up to 10000:1 with Tp>98%@CW with 120*60mm aperture.
Application:
Medical Laser system
Industrial Q-Switch Laser system
