Figure 4: Improved focal spot characteristics.
From: Perfect X-ray focusing via fitting corrective glasses to aberrated optics
(a) Horizontal slice (x-direction, logarithmic scale) through the focal plane depicted in Fig. 3b,e and for an ideal lens. (b) Radially integrated intensity distribution around the centre of the focal spot. The solid green line represents the results for the uncorrected lens (without the phase plate), the dotted blue line represents the phase plate corrected lens, and the dashed red line represents the modelled aberration-free lens in both a,b.
