FOCtek specially designed a high transmission Glan Laser Polarizer for online_ordering which requires high transmission. The specially designed polarizer is based on the Brewster Cut crystal, which can improve the transmission from normally >85% to 95%. This polarizer can be made from both Calcite and YVO4.

Features:
  • Air-spaced
  • All Brewster's angle Cutting.
  • Mounted with escape windows.
  • High Polarization purity.
  • Suitable for high power online_orderings.
  • High transmission.
  • Brewster angle input.
