Wollaston
prism
A device, invented by William Wollaston,
that separates randomly polarized or unpolarized light into two orthogonal
linearly polarized beams that exit the prism at an angle determined by the
wavelength of the light and the length of the prism. Wollaston prisms are
used in some kinds of polarimeter.
