Electro Optical Components, Inc. Wollaston / Rochon Prism Polarizing Beam Splitters

Wollaston Type Wollaston prism polarizing beam splitters consist of two equal angle calcite prisms optically coupled with optic axis orthogonally crossed to the direction of propagation. The beam separation of about 20° is then approximately balanced about the input beam axis. The transmission range for cemented prisms of 0.32 to 2.5µm to 18° at 2.5µm. They come un-mounted or in the optional mount pictured to the right. Rochon Type In this arrangement one polarization state is transmitted undeviated through the prism while the orthogonal component is deviated approximately 10°. The straight through component is clearly chromatic while the deviated beam varies from 11° at 0.32µm to 8.5° at 2.5µm.
