http://depthome.brooklyn.cuny.edu/physics/lab/phy2/newlabs/Diffraction-grating-ver-2.pdf WebThe grating is used as a dispersive element to disperse the wavelengths of light. Properties of the grating do not only include its dispersion range but also influence the optical resolution by the number of grooves. A second parameter of the grating, its blaze wavelength, determines the optimal efficiency at various wavelengths.

WebIn dispersive array spectrometers, there are 3 main factors that determine the spectral resolution of a spectrometer: the slit, the diffraction grating, and the detector. The slit determines the minimum image size that the optical bench can form in the detector plane. WebOptical spectrometers (often simply called "spectrometers"), in particular, show the intensity of light as a function of wavelength or of frequency. The different wavelengths of light are separated by refraction in a prism or by diffraction by a diffraction grating. Ultraviolet–visible spectroscopy is an example.
