The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a device for obtaining completely or partially polarized light from light with arbitrary polarization characteristics. It is the simplest polarizing device and one of the main elements in more complex devices. Linear polarizers, which produce plane-polarized light, take the form of optically anisotropic polarizing prisms, polarizing sheets, and optical piles of isotropic plates transparent in a given region of the spectrum. A combination of a linear polarizer with quarter-wave plates is used to obtain circularly polarized light. Any polarizer can also be used as an analyzer of polarized radiation.
