Figure 2
Simulated focus profile for a one-dimensional lens. A wavefront modified to give a focus beam size of 5 µm (green: geometrical optics; red: physical optics). Bottom: a coherent source. Top: an incoherent Gaussian profile source with r.m.s. size 8 µm (equivalent to an X-ray undulator source at the Diamond synchrotron). The X-ray energy is 15 keV, Q is 400 mm and P is 45 m.
