Wollaston Polarizers

Wollaston polarizer is designed to separate unpolarized light beam into two orthogonally polarized ordinary and extraordinary components which are symmetrically deflected from axis of initial propagation. This kind of performance is attractive for laboratory experiments as both – ordinary and extraordinary beams are accessible. Wollaston polarizers are used in spectrometers also can be used as polarization analyzers or beamsplitters in optical setups.
