dichroism
Sign in to savethumb|right|lampworking|Lampworked [[dichroic glass bead]] In optics, a dichroic material refers to: a material which causes visible light to be split up into two distinct beams of different wavelengths (colours), one of which is reflected and one of which is transmitted (not to be confused with dispersion), or a material in which light rays having different polarization directions are absorbed differently.

== Etymology == The term is derived from the Greek dichroos, meaning "two-colored," referring to the optical effect where a substance appears to have different colors when viewed from different angles or through different polarizations.
