Scalar Diffraction Efficiency Calculations (A/0@f1#
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted beZ(o?uK
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The oP,9#FC|(
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths GlR~%q-jiQ
of the rays are determined by the grating order and local grating spacing. For more details about how the ,

diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency Vm8D "I5i
Calculations” on page 4-116.
