Scalar Diffraction Efficiency Calculations l>Av5g)
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted Mq+<mX7
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The ua#K>sur.
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths ]

of the rays are determined by the grating order and local grating spacing. For more details about how the 9ECS,r*B
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency (#u{ U=
Calculations” on page 4-116.
