Product Description

General introduction:
Diffraction grating is a kind of optical device using diffraction phenomenon, that is, a kind of diffraction optics. It contains a periodic structure that results in spatially varying optical amplitude and/or phase changes. The most common are reflection gratings, in which the reflecting surface has periodic surface fluctuations, resulting in position-dependent phase changes.

Product principle:
Gratings are also called diffraction gratings. It is an optical element that disperses (decomposes into a spectrum) light by using the principle of multi-slit diffraction. It is a flat glass or metal sheet engraved with a large number of parallel equal-width, equidistant slits (scribed lines). The number of slits in the grating is very large, generally tens to thousands per millimeter. The monochromatic parallel light passes through the diffraction of each slit of the grating and the interference between the slits, forming a pattern with very wide dark fringes and very fine bright fringes. These sharp and bright fringes are called spectral lines. The position of the spectral line varies with the wavelength. When the polychromatic light passes through the grating, the spectral lines of different wavelengths appear in different positions to form a spectrum. The light passing through the grating to form a spectrum is a common result of single-slit diffraction and multi-slit interference.
