Brewster-type thin film polarizers

Main features

 

  • Substrates fabricated from high-quality UV grade fused silica optical glass
  • Designed for most popular laser line and harmonic wavelengths
  • The angle of incidence: Brewster-angle
  • Typical extinction ratio Tp:Ts > 200:1
  • Custom dimensions, the operating wavelength available upon request

 

Application examples

 

  • Polarization separation
  • Optical isolation
  • Polarization cleaning

  • Curves
  • Standard specification

4Lasers standard Brewster-type thin-film polarizers are designed for applications, which include polarization separation. These elements provide a moderately extinction ratio Tp:Ts > 200:1 and are 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.
