Rochon prism
An optical device consisting of two quartz prisms; the first, cut parallel
to the optic axis, receives the light; the second, with the optic axis at
right angles, transmits the ordinary ray without deviation but the extraordinary
ray is deflected and can be absorbed by a screen. A Rochon prism can be
usd to produce plane-polarized light and it can also be used with ultraviolet
light. Related category
