Rochon Prism Polarizers, Only Ordinary Ray Undeviated
Overview:
A Rochon Prism is a type of polarizer. It is made from two prisms of a birefringent material such as crystal quartz and YVO4 which are cemented together.
Rochon Prisms split an arbitrarily polarized input beam into two orthogonally polarized output beams. The ordinary ray remains on the same optical axis as the input beam, while the extraordinary ray deviates by an angle, which depends on the wavelength of the light and the material of the prism (see the Beam Deviation graphs in the table to the right). The output beams have a high polarization extinction ratio of >10 000:1 for the quartz prism and >100 000:1 for the YVO4 prism.
Rochon Prims are used for applications where small beam separations are required.
