Znse thin film polarizer


Thin Film Polarizer is used to split a laser beam into two parts with S and P Polarizations.Conversely, Thin Film Polarizer 's can be used to combine two beams with S and P polarizations.

Thin Film Polarizer 's consist of a coated plate, which is oriented at Brewster's angle with respect to the incoming beam. The thin film coating will enhance the reflectivity of the s-polarized component of the beam, while maintaining high transmission of the p-polarized component.
