Scalar Diffraction Efficiency Calculations e:9EP,
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted qVE0[ve
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The `!HD.
E[2c
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths o"
,8
of the rays are determined by the grating order and local grating spacing. For more details about how the >dt*^}*
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency M[YFyM(
Calculations” on page 4-116.
