Scalar Diffraction Efficiency Calculations ~)_K"h.DY
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted }*h47t}
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The Zgy7!AF!
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths aFyh,
of the rays are determined by the grating order and local grating spacing. For more details about how the >d#3|;RY
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency Sg_O?.r
Calculations” on page 4-116.
