order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The =T$- #bA)
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths ),,vu
of the rays are determined by the grating order and local grating spacing. For more details about how the `,d7_#9'
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency 3v U (4}@
