CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted vM_:&j_?``
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The lsN~*q?~]
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths u.rY#cS,-R
of the rays are determined by the grating order and local grating spacing. For more details about how the {mB0rKVm
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency d;n."+=[x
