Feather of a gray catbird. (a) Large-area coarse-resolution image in (left) transmission contrast and (right) S Kα fluorescence. Incident energy 2700 eV, beam spot size 10 µm × 5 µm and pixel size 10 µm. (b) Higher-resolution image, spot size 3 µm × 3 µm and pixel size 2 µm; (top) S fluorescence and (bottom) transmission contrast. Note that parts of the sample are not all in the same plane. |
