CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted 0i\M,TNf*
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The waj0"u^#
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths f@|A[>"V
of the rays are determined by the grating order and local grating spacing. For more details about how the Zm_UR*"
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency +Z!)^j
Calculations” on page 4-116.
