A special form of a blazed grating is the echelle grating. It is characterized by particularly large blaze angle (>45°). Therefore, the light hits the short legs of the triangular grating lines instead of the long legs. Echelle gratings are mostly manufactured with larger line spacing but are optimized for higher diffraction orders. Echelle gratings are useful in planet-finding astronomy, and are used on the successful HARPS and … Webmaximum tilt that the grating may have with respect to gravity. As a typical diffraction angle into the ﬁrst-order maximum is 25mrad, one can tolerate a tilt angle of (at most) about one mrad before molecules start falling from one diffraction order into the trajectory of a neighbouring order of a different velocity class. The WebThis helpful tool allows one to graphically explore the dependence of diffraction angle, angular dispersion, and temporal dispersion on angle of incidence and wavelength for light incident on a grating with a certain frequency.
