Polarizer-Analyzer-Attenuator
Polarizer-Analyzer-Attenuator
Polarizer-Analyzer-Attenuator is a stacked series of ZnSe plates placed at Brewster’s angle to an incoming beam. At each plate, virtually all of the p-polarized component is transmitted, while most of the s-polarized component is reflected. The net result, after the beam has traversed several plates, is a beam which is virtually only p-polarized.

Applications
  • Unpolarized beam polarization
  • Laser beams polarization analysis
  • Continuously variable attenuation of linearly polarized beams
  • Electro-optic modulation systems
Features
  • High-power handling
  • Visible transmission for easy alignment
  • Low-insertion loss
  • High-extinction ratio (> 500:1)
  • Broadband operation (2 to 14 µm)
  • Optional exit port or heat sink cooling
