ZnSe Thin Film Polarizers
Thin film polarizers (TFP series) are used to split a laser beam into two parts with S and P Polarizations. Meanwhile, they can also be used to combine two beams with S and P polarizations. They consist of a coated plate, which is oriented at Brewster’s angle with respect to the incoming beam. The thin-film coating is able to enhance the reflectivity of the s-polarized component of the beam and maintain high transmission of the p-polarized component.
