Wollaston Prism Polarizers Quartz

Wollaston Prism Polarizer is made of two birefringent material prisms thatare cemented together. The deviations of the ordinary and extraordinary beamsare nearly symmetrical about the input beam axis, so that Wollaston polarizingbeam splitter has approximately twice the deviation of the Rochon. Theseparation angle exhibits chromatic dispersion, as shown in the blow. Anyseparation angle can be designed upon the requirement. The separation angle ofstandard products versus wavelength is shown in the plot below. Wollaston Polarizer has advantages of very wide wavelength range, low power application, broadband 10000 : 1 extinctionratio, both ordinary andextraordinary beams are deviated, besides, it suits for lowpower application and where the large deviation is required.
