Scalar Diffraction Efficiency Calculations v08Xe*gNU
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted @u }1 S1
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The 5t&;>-A'?'
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths zw,=mpf3_
of the rays are determined by the grating order and local grating spacing. For more details about how the j)neVPf%v
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency h1`u-tc2x
Calculations” on page 4-116.
