X-ray beams after correction with a phase plate as characterized by ptychography. (a) Horizontal beam caustic at 8.2 keV after correction with the diamond phase plate shown in Fig. 5(a). (b) Intensity distribution in the plane with highest peak intensity, marked by the dashed line in (a). (c) Horizontal beam caustic at 35 keV after correction with the polymer phase plate shown in Fig. 5(c). (d) Intensity distribution in the plane with highest peak intensity, marked by the dashed line in (c). |
