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
- 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
