A device used to break light into its component wavelengths. It is usually composed of a material with tiny grooves cut into it which disperses the light as it passes through or bounces off the grating (depending on the type of grating). Physicists and astronomers often use diffraction gratings to study the nature of light. See also disperson, spectrum
A very closely ruled series of lines that, through their diffraction of light, provide a spectrum of radiation that falls on it.
Grating device that splits light into a spectrum of the component wavelengths.
An array of fine, parallel, equally spaced reflecting or transmitting lines which diffract light into a direction characteristic of the spacing of the lines and the wavelength of the diffracted light.
An optical surface, either transmitting or reflecting, with several thousand equally spaced and parallel grooves ruled in it.
A grooved optical element that has been deformed to reflect light of many colors. It acts like a prism to produce a spectrum.
optical device consisting of a surface with many parallel grooves in it; disperses a beam of light (or other electromagnetic radiation) into its wavelengths to produce its spectrum
a bunch of really, really, small rectangular openings called slits packed close together on a single sheet of material (usually plastic or glass)
a glass or polished metal surface on which a large number of very fine, parallel grooves or slits are cut
a grooved mirror that functions as a prism, only more reliably and with less weight
an array of finely spaced lines that separates electromagnetic radiation like X-rays into a range of wavelengths, just like a prism separates sunlight into all the colors of the rainbow
an optical component that in normal use separates (diffracts) polychromatic (white) light into its component wavelengths
an optical component that separates light into its constituent wavelengths
an optical element that diffracts energy into its constituent wavelengths
a plate of transparent material, one side of which is covered by closely spaced, parallel, opaque lines (the spacing is equal to several wavelengths of the light involved)
a row of fine parallel lines or grooves, usually on a reflective surface
a series of fine lines scribed on a transparent substrate, with a spacing slightly larger than the wavelength of visible light
a set of parallel slits used to disperse light using Fraunhofer diffraction
a set of regularly spaced slits (or obstacles)
a sheet of film (transmission grating) or a mirror (reflection grating) with a series straight scratches spaced only a few wavelengths apart
a slit (or slits) in a wall designed to allow a wave to pass through
a surface that has been scratched with a pattern of very closely-spaced lines
a thin piece of glass with thousands and thousands of thin parallel lines etched into its surface
a tool whose operation is based on the diffraction of light
a "truth-teller" for light
A device that splits light into its different colours, which is known as a spectrum.
A mirror with very fine grooves that separates light into its different colours on reflection.
optical device made of glass or metal etched with thousands of closely-spaced lines . The grooves produce interference patterns in light. There are two types; transmission gratings allo the light to pass through, while reflection gratings reflect the light away.
Material containing many parallel lines very closely spaced that produces a light spectrum by interference.
A device formed on a substrate with a regular structure, which diffracts light. Electric field An electric field is the set of lines of force that act on charged particles. A light wave will impose an oscillating force on a charged particle. Because atoms are made of charged particles, the electric field controls the way in which light is absorbed and emitted.
A glass surface into which fine grooves have been cut, allowing light to be "spread" into its component colors, creating a spectrum. The groove dimensions correspond to wavelengths of light, usually around 500 nm (green).
a large number of parallel, equally spaced slits
A mirror ruled with thousands of closely spaced parallel lines, thus causing reflected radiation to spread into its constituent wavelengths and frequencies.
optical attachment that separates light into its constituent colors.
A device that splits light into its component parts or spectrum. A diffraction grating often consists of a mirror with thousands of closely spaced parallel lines, which spread out the light into parallel bands of colors or distinct fine lines or bars.
An array of fine, parallel, equally spaced reflecting or transmitting lines that mutually enhance the effects of diffraction to concentrate the diffracted light in a few directions determined by the spacing of the lines and by the wavelength of the light.
A sheet, film, or screen with a pattern of equally spaced slits. Typically the width of the slits and space between them is chosen to generate a particular diffraction pattern.
In optics, a diffraction grating is a reflecting or transparent element, whose optical properties are periodically modulated. Most commonly the diffraction gratings are realized as fine parallel and equally spaced grooves or rulings on material surface. When light is incident on a diffraction grating, diffractive and mutual interference effects occur, and light is reflected or transmitted in discrete directions, called diffraction orders.
