Figure 11
Absorption (left) and DPC (right) images of a diatom (phytoplankton cell) recorded at 10 keV photon energy at beamline 2-ID-E. As above, the specimen is completely invisible in absorption, but clearly visible in phase contrast. We have used the same 100 nm-outermost-zone-width zone plate as above, a step size of 100 nm and a pixel dwell time of 2 ms.
