这方面,CODE V 确实比ZEMAX 强一些: 1U,1)<z~u
Scalar Diffraction Efficiency Calculations 5H9r=a
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted -uH#VP{0M
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The 8+Td-\IMk
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths g%k`
of the rays are determined by the grating order and local grating spacing. For more details about how the c1xrn4f@a
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency . ]8E7
Calculations” on page 4-116.
