CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted ]x).C[^
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The =),O ;M
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths 6.9C4
of the rays are determined by the grating order and local grating spacing. For more details about how the RH{+8?0
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency dt@~8kS
Calculations” on page 4-116.
