Wollaston Prisms

Wollaston prisms split a beam into two orthogonally polarized divergent beams, both almost equally deviated. They consist of two equal prisms made from the finest optical grade natural calcite, giving useful transmission over the 300-2200 nm range; the angular separation of the output beams depends on wavelength. Prisms are offered in several sizes with different beam separation angles, unmounted or mounted.
