这方面,CODE V 确实比ZEMAX 强一些: #cY[c1cNv
Scalar Diffraction Efficiency Calculations E1QJ^]MG.
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted mb*Yw6q
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The s$fM,l:!
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths R_EU|a
of the rays are determined by the grating order and local grating spacing. For more details about how the H!;N0",]N
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency 8qe[x\,"8
Calculations” on page 4-116.
