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

Spiricon has the most extensive array of accessories for beam profiling existing. There are components for attenuating, filtering, beam splitting,
magnifying, reducing and wavelength conversion. There are components for wavelengths from the deep UV to CO2 wavelengths. Most of the
components are modular so they can be mixed and matched with each other to solve almost any beam profiling requirement needed.
