  • Curves
  • Standard specification

4Lasers standard Brewster-type thin-film polarizers are designed to be used for applications, which include polarization separation. These elements provide moderately extinction ratio Tp:Ts > 200:1 and perfectly fit for high-power and UV applications. 4Lasers design and manufacture standard and custom Brewster type polarizers in the range of 230 nm and 2000 nm with face dimensions up to 160 mm.
