What Wikipedia says

A Wollaston prism is an optical device, invented by William Hyde Wollaston, that manipulates polarized light. It separates light into two separate linearly polarized outgoing beams with orthogonal polarization. The two beams are polarized according to the optical axis of the two right angle prisms.
