CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted E?mp6R]}%
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The X-,y[ )
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths =)YYx8gR
of the rays are determined by the grating order and local grating spacing. For more details about how the fB96Q
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency ws?s
Calculations” on page 4-116.
