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.
