Rochon Polarizer is used to split an arbitrary polarized incoming light beam into two orthogonal and polarized outgoing light beams. The ordinary ray will continue along the same optical axis of the incoming light beam, whereas the extraordinary ray will have a slight deviation in its angle. This is dependent on the wavelength of the incoming light beam as well as the material of the Rochon Polarizer. The output beams have a high polarization extinction ratio accordingly to their material.

Quartz are excellent birefringent crystals. Due to its high UV, VIS, and NIR transmittance, and its ability to rotate polarized light and high damage threshold, it is very useful for transmittance from 190-2900nm wavelength. With high hardness properties, it is commonly used in the retardation plate. Quartz can exhibit circular birefringence allowing the ordinary and extraordinary beam to propagate with the same velocity using the same refractive index. Hence its effect is useful in rotators.
