Scalar Diffraction Efficiency Calculations Pn.bVV:
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted Ol /\t
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The e0,'+;*=g
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths K-vWa 2
of the rays are determined by the grating order and local grating spacing. For more details about how the 66&EBX}
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency IV 16d
Calculations” on page 4-116.
