Wollaston Polarizers

Wollaston Polarizers

Wollaston polarizer is made  of two birefringent material prisms that are cemented together. The  deviations of the ordinary and extraordinary beams are nearly  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 blow.  Any separation angle can be designed upon the requirement. The  separation angle of standard products vs wavelength is shown in the plot  below.
