Figure 8
Alternative optical scheme for the monochromator proposal in Fig. 2[link], which can provide high spectral resolution in blaze-maximum tuning without beam collimation. The aberrations arising in the off-plane diffraction from the plane grating with constant groove density can be eliminated in the divergent beam when an astigmatically focusing crossed mirror pair is operated in an inclined orientation with respect to the laboratory frame. As already indicated in Fig. 2[link], also here the exit slit needs to be inclined with respect to the vertical direction by the same angle calculated according to equation (4)[link].
