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.
