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.
