WebThis binary profile is an equally good approx-imation of an ideal blaze in the opposite direction, so it follows that this grating is also 40.5% efficient in the −1 diffraction … A blazed grating – also called echelette grating (from French échelle = ladder) – is a special type of diffraction grating. It is optimized to achieve maximum grating efficiency in a given diffraction order. For this purpose, maximum optical power is concentrated in the desired diffraction order while the residual … See more Like every optical grating, a blazed grating has a constant line spacing $${\displaystyle d}$$, determining the magnitude of the wavelength splitting caused by the grating. The grating lines possess a triangular, sawtooth-shaped … See more • Richardson Gratings, "Technical Note 11 - Determination of the Blaze Wavelength" (30 September 2012) • Horiba Scientific, "Diffraction Gratings" (30 September 2012) See more Blazed gratings can also be realized as transmission gratings. In this case the blaze angle is chosen such that the angle of the desired … See more A special form of a blazed grating is the echelle grating. It is characterized by particularly large blaze angle (>45°). Therefore, the light … See more charlie nathanson
