grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths (#u{ U=
of the rays are determined by the grating order and local grating spacing. For more details about how the w%u5<
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency -1m vhR~
