WOLLASTON POLARIZERS

Wollaston polarizer is made of two birefringent material prisms that are cemented together .The deviations of the ordinary and extraordinary beams symmetrical about the input beam axis.so that the Wollaston polarizing beam splitter has approximately twice the deviation of the Rochon.The separation angle exhibits chromatic dispersion, as shown in the plot blow.Any separation angle can be designed upon requirement .The separation angle of standard products vs wavelength is shown in the plot below.
