Abstract

On the base of electromagnetic theory of gratings, we analyse the effects of both of two important parameters of classical blaze grating in Littrow mount to diffraction efficiency, and the two parameters are optimized for obtaining highest diffraction efficiency. It is presented that not only blaze angle but apex angle affect diffraction efficiency. The investigation has been performed on the design and fabrication of classical blaze grating which has high diffraction efficiency.
