Scalar Diffraction Efficiency Calculations 4Cm+xAXG
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted Q0l[1;$#
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The $^~dqmE2,
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths ,%Sf,h?"^
of the rays are determined by the grating order and local grating spacing. For more details about how the TuR.'kE@
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency w\SfzJN
Calculations” on page 4-116.
