CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted %z=le7
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The zVViLUwG
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths `+]Qz =}
of the rays are determined by the grating order and local grating spacing. For more details about how the ? >7[7(|
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency W: z6Koc0
Calculations” on page 4-116.
