monochromator
/mon'euh kroh"may teuhr/, n. Optics.
a spectroscope with a slit that can be moved across the spectrum for viewing individual spectral bands. Also called monochromatic illuminator.
[1905-10; MONOCHROMAT(IC) + (ILLUMINAT)OR]

▪ scientific instrument
      instrument that supplies light of one colour or light within a narrow range of wavelengths. Unwanted wavelengths (colours) are blocked by filters (first used by Bernard Lyot in the 1930s) or bent away, as in the spectroheliograph. The monochromator is used to photograph the Sun and to study photochemical effects; it is usually a component of a spectrophotometer.
