• grating —    A reflective surface covered with evenly spaced, microscopic grooves, whose purpose is to separate the individual wavelengths from “white” light. The distance between grooves and the angle of the faces are determined by the wavelengths to be… …   Forensic science glossary

• Diffraction grating — A very large reflecting diffraction grating. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The directions of these beams …   Wikipedia
