Fused Quartz optical Brewster window

Fused Quartz optical Brewster window
  • Brewster window plate is usually used for polarization in laser cavity. When placed at Brewster angle, the p polarization component of the beam will be completely transmitted, and the S polarization component will be partially reflected, so as to increase the loss of S component in the cavity.

  • Quartz glass is an ideal UV material. It has high transmittance in the range of 220nm to 2500nm, good chemical stability and radiation resistance, low expansion coefficient, low fluorescence radiation and scratch resistance.
