NICOL PRISM

nĭkˈəl, optical device invented (1828) by William Nicol of Edinburgh. It consists essentially of a crystal of calcite, or Iceland spar, that is cut at an angle into two equal pieces and joined together again with Canada balsam. An ordinary beam of light entering the crystal undergoes double refraction, i.e., is split into two parts, each of which is affected in a different way. One of these parts, the so-called ordinary ray, undergoes total reflection at the Canada-balsam joint and is turned off from its course to pass out at one side of the crystal. The other ray, the extraordinary ray, passes on through the crystal. By means of this device a beam of light can be polarized (see polarization of light) or a beam of polarized light can be subjected to analysis. The principle involved has been applied to the microscope in the illumination of the field.
