A diffraction grating is a optical material or device that is usually designed to break up white light into the various colors of the visible spectrum.laze angles are used to concentrate a diffraction grating output on a certain band region of the light spectrum. This is done to obtain a maximum resolution in a particular band of light known as the Blaze wavelength.
A diffraction grating is the tool of choice for separating the colors in incident light. This illustration is qualitative and intended mainly to show the clear separation of the wavelengths of light. There are multiple orders of the peaks associated with the interference of light through the multiple slits.
