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 depend on the spacing of the grating and the wavelength of the light so that the grating acts as ...

An optical device used to disperse light into a spectrum. It is ruled with closely-spaced, fine, parallel grooves, typically several thousand per cm, that produce interference patterns in a way that separates all the components of the incoming light. A diffraction grating can be used as the main dis...

Polished metallic surface (usually a metallic mirror on a block of glass or quartz) or plastic surface on which has been ruled a great number (in thousands) of thin, parallel lines with small gaps between them, used to split light to produce a spectrum. A beam of light travelling through the narrow ...

A diffraction grating is an optical component that separates light into its constituent wavelengths. Functionally equivalent to a prism, it disperses the light into its spectrum by employing grooves to diffract the light. The angle of the diffraction is a function of the wavelength.
