CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted bo%v(
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The g-cC&)0Q
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths Ag#o&Y
of the rays are determined by the grating order and local grating spacing. For more details about how the 8 ta`sNy9
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency /H m), 9NN
Calculations” on page 4-116.
