Beam sampler / attenuator II VI INFRARED

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
