diffraction grating

n.
A polished surface, usually glass or metal, having a large number of very fine parallel grooves or slits, and used to produce optical spectra by diffraction of reflected or transmitted light.

diffraction grating

n
(General Physics) a glass plate or a mirror with a large number of equidistant parallel lines or grooves on its surface. It causes diffraction of transmitted or reflected light, ultraviolet radiation, or X-rays
