Figure 14
Absorption (left) and DPC (right) images of 5 µm-diameter polystyrene spheres recorded at 2500 eV photon energy at beamline 2-ID-B. At this photon energy the spheres are visible in absorption, but show much more detail in DPC. The pedestal around the spheres is due to residual solution, and the small bump on the right-hand sphere is due to radiation damage caused by a 30 s exposure to the focused X-ray beam. This scan was performed with a 50 nm-outermost-zone-width zone plate, 25 nm steps and 5 ms dwell time.
