A grating that is in a configuration in which it is blazing is said to be in the blaze condition. It is important to recognize that it is the characteristics of the grating as well as the conditions under which it is illuminated that contribute to the condition known as blazing.The measure of the light intensity diffracted from a grating is called its efficiency. The blaze wavelength is defined as that wavelength, in a given diffraction order m, for which the efficiency curve reaches its maximum. It has long been known that diffraction gratings can, in certain configurations, concentrate a large percentage of the energy incident on them into a specific diffraction order. This phenomenon has come to be called blazing.
