Spectral scan of titanium film. (a) The blue line shows the aborption spectrum taken with the condenser remaining stationary from the center of the field of view; the red line shows the absorption spectrum from the integral of the whole image with the condenser in `scanning' mode to produce uniform illumination. (b) TiO2 absorption spectral scan. Blue line from XM-2, red line from ALS beamline 5.3.2, a scanning transmission X-ray microscope (STXM). |
