Crystal Polarisers The basic Glan-Taylor polarising prism gives excellent extinction and high transmittance over a wide wavelength range. The form with side faces polished is useful as a polarising beamsplitter or for high powers. The high-transmittance type, also with side windows, has all four surfaces at Brewster’s angle for the transmitted beam, so reflection losses are negligible. The Wollaston polarising beamsplitter, a cemented type, deviates the two polarisation components of a beam at angles ±10 degrees from input direction, with a small chromatic dispersion. Most types are also listed mounted in flanged clevis mounts, these fit directly, for instance, into our rotating holders and Tube Mount system, whilst still allowing access to the side exit beam.
