Blazed Gratings Blaze is defined as the concentration of a limited region of the spectrum into any order other than the zero order. Blazed gratings are manufactured to produce maximum efficiency at designated wavelengths. http://www.horiba.com/scientific/products/o ptics-tutorial/diffraction-gratings/ Blaze grating Question: is it a useful grating if most of energy is concentrated in the zeroth order?
