Quick Reference. A device for producing plane-polarized light (see polarizer). It consists of two pieces of calcite cut with a 68° angle and stuck together with Canada balsam. Nicol prisms are very expensive and bulky, and have a very limited aperture, which restricts their use at high magnifications. Instead, polarized light is now most commonly produced by absorption of light having a set of specific vibration directions in a dichroic medium. A Nicol prism.
