Scalar Diffraction Efficiency Calculations feG#*m2g
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted =9L1Z \f
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The sG8G}f
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths JpC_au7CX
of the rays are determined by the grating order and local grating spacing. For more details about how the 2tI ,`pSU
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency ^s_7-p])(
Calculations” on page 4-116.
