Scalar Diffraction Efficiency Calculations ;w1?EdaO
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted EgIFi{q= 0
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The -L7Q,"a $
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths fd >t9.
of the rays are determined by the grating order and local grating spacing. For more details about how the b ;\qF &T
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency >O[# 661
Calculations” on page 4-116.
