Scalar Diffraction Efficiency Calculations z@VL?A(3
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted $\ZWQct
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The #8h7C8]&
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths D\5+2 G
of the rays are determined by the grating order and local grating spacing. For more details about how the In1{&sS
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency 79 ;uHR&S
