A partition, covering, or frame of parallel or cross bars; a latticework resembling a window grate; as, the grating of a prison or convent.
A system of close equidistant parallel lines or bars, esp. lines ruled on a polished surface, used for producing spectra by diffraction; -- called also diffraction grating.
A surface ruled with closely spaced lines that, through diffraction, breaks up light into its spectrum.
An open grid assembly of metal bars, in which the bearing bars, running in one direction, are spaced by rigid attachment to cross bars running perpendicular to them or by bent connecting bars extending between them.
An open grid assembly of metal bars in which the bearing bars, running in one direction, are spaced by rigid cross bars attached to them.-Bar An extruded aluminum bearing bar having a cross sectional shape resembling the letter "I".
Welded framework of crossbars used in flooring of equipment platforms, platform walkways, catwalks and stair treads.
a barrier that has parallel or crossed bars blocking a passage but admitting air
a frame of iron bars to hold a fire
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 reflective surface, scored either mechanically or holographically with parallel grooves that can be designed for different wavelength regions
a diffraction/refraction dispersion element used to separate radiation into component wavelengths. Consist of a series of grooves of lines "blazed" onto a piece of quartz or silicon. These lines are parallel and closely spaced (10-2000 per mm). Constructive interference at certain incidence angles produces monochromatic radiation at specific diffraction angles. Multiple order effects also produce radiation at one half, one third, one quarter... of the primary order (longest wavelength) radiation at the same diffraction angle.
A grating is a component of the spectrophotometer which disperses white light inot a continuos spectrum of colors. The angle of the grating with respect to the incident light determines the wavelength of light which will ultimately pass through the sample solution.
Optical device which has a fine regular pattern used to disperse electromagnetic radiation into a spectrum. A transmission grating consists of a large number of narrow, closely spaced bars. A reflection grating consists of narrowly spaced saw-teeth or steps ruled on a polished surface such as glass or metal.
a framework of crossed or parallel metal bars, placed across an opening or as flooring on platform eg a catwalk, to allow air to flow freely or to allow view below walkway
A pattern of light and dark lines which will diffract light. A simple linear grating will disperse white light into a spectrum of colors. Holographic gratings can produce many spectra, focused to different distances. An image hologram is essentially an extremely complex grating.
Material onto which microscopic parallel lines are inscribed. used to create a spectrum of colors from light
an open grid of metal bars. The grid bars are attached to cross bars that run perpendicular to them or to bent connecting bars which extend between them.
1. A frame of metal bars to hold fuel in a fireplace or stove. 2. Evenly-spaced metal bars at right angles making a framework that covers openings of drains, etc. and restrains large objects from flowing through.
A grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets, in which case the second set is usually perpendicular to the first (as illustrated). When the two sets are perpendicular, this is also known as a grid.
