Scalar Diffraction Efficiency Calculations _4{3^QZq5
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted +pv..\
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The l7WZ" 6d
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths 0p,_?3nX
of the rays are determined by the grating order and local grating spacing. For more details about how the =%77~q-HL
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency q@mZ0D-
Calculations” on page 4-116.
