CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted :o$k(X7a
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The '0QrM,B9
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths !{'C.sb?~
of the rays are determined by the grating order and local grating spacing. For more details about how the |F)BKo D
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency px6[1'|g
Calculations” on page 4-116.
