WebA diffraction grating is an optical device exploiting the phenomenon of diffraction, i.e., an kind of diffractive optics . It contains a periodic structure, which causes spatially varying optical amplitude and/or phase changes. Like every optical grating, a blazed grating has a constant line spacing , determining the magnitude of the wavelength splitting caused by the grating. The grating lines possess a triangular, sawtooth-shaped cross section, forming a step structure. The steps are tilted at the so-called blaze angle with respect to the grating surface. Accordingly, the angle between step normal and grating normal is .
