Wollaston Polarizer

These Wollaston polarizers are made of two birefringent crystal prisms which 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. The separation angle vs wavelength is shown in the following table based on our standard products. Different separation angle can be designed upon request.
