CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted @?ntMh6
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The JmN,:bI
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths Q)N$h07R
of the rays are determined by the grating order and local grating spacing. For more details about how the FkJa+ZA
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency [XFZ2'OO
Calculations” on page 4-116.
