PURPOSE: Show polarization by the classic Nicol prism.
DESCRIPTION: A Nicol prism, formed by a cut calcite crystal, uses total internal reflection of one of the two polarization components to achieve polarization of a light beam. The object (a letter F in a baffle) is focussed by a lens onto a distant screen, with the Nicol prism between the object and the lens. Polarization can be verified by rotating either the Nicol prism or the polaroid, at the right in the photograph.
