WebMar 31, 2024 · A surface such as the Diffraction Grating surface has constant period of grating lines along one axis, and is commonly used in spectrometers. The real power of computer-generated diffractive surfaces is that the grating period can be made to vary spatially across the surface, so that diffractive power can be added exactly where it is … WebDiffraction gratings are commonly used for spectroscopic dispersion and analysis of light.

WebBasically, a spectrometer is an optical system consisting of two lenses or mirrors that produce an image of the input slit on the detector. In between the lenses or mirrors, a diffraction grating is placed that disperses different wavelengths from different angles. WebSep 12, 2024 · Diffraction gratings are commonly used for spectroscopic dispersion and analysis of light. What makes them particularly useful is the fact that they form a sharper pattern than double slits do. That is, their bright fringes are narrower and brighter while their dark regions are darker.
