Monochromator information


Conceptual animation of the dispersion (or breaking down) of light
Monochromator in an x-ray beamline at the Advanced Photon Source, Argonne National Laboratory.

A monochromator is an optical device that transmits a mechanically selectable narrow band of wavelengths of light or other radiation chosen from a wider range of wavelengths available at the input. The name is from the Greek roots mono-, "single", and chroma, "colour", and the Latin suffix -ator, denoting an agent.
