Introduction:
The Wollaston Prism offers the widest deviation angle of beam displacing polarizers. Both output beams are deviated symmetrically to within 1-Deg. Since the output deviations are chromatic, Wollaston prisms have been used in spectrometers as well as polarization analyzers. The Wollaston prism polarizer is made of two calcite prisms cemented together.
