Wollaston Polarizers

Wollaston Polarizers


Wollaston polarizers consist of two identically shaped prisms made from a birefringent crystal. The crystal axes of the two prisms have orthogonal orientation. This results in a deviation of the beams having ordinary and the extraordinary, respectively by approximately the same angle but with opposite sign. In Wollaston polarizers both output beams show a high extinction ratio over the entire transmission range. The directions of polarization are parallel and orthogonal to the splitting plate, respectively.

We provide the Wollaston prisms by default in a cylindrical holder and without antireflection coating.

Wollaston prisms are available from calcite as well as from quartz. For both crystals we use material free of striae and bubbles. Calcite allows to achieve larger splitting angles between the two output beams (standard angles: 5°, 10° and 20°) . For quartz the splitting angles are smaller owing to the lower birefringence (standard angles: 0,5° and 1°). The advantages of quartz are the better transmission in the deep UV as well as the availability of larger dimensions.

The given splitting angles always refer to the full angle between the beams at the output.
