CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted e^!>W %.7Z
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The D[jPz0
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths ,:[\h\5m
of the rays are determined by the grating order and local grating spacing. For more details about how the q,;8Ka )
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency Rtywi}VV2
Calculations” on page 4-116.
