Scalar Diffraction Efficiency Calculations ,Sg33N ?
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted 6/1$< !WH
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The Pl78fs"L@
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths eFFc 9'o
of the rays are determined by the grating order and local grating spacing. For more details about how the [s}/nu~U
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency wf9z"B
Calculations” on page 4-116.
