Scalar Diffraction Efficiency Calculations g5EdW=Dt,
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted JlR'w]d M,
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The L"i
B'=
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths s eFug
of the rays are determined by the grating order and local grating spacing. For more details about how the X^tVq..0
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency J,s)Fu\j@
Calculations” on page 4-116.
