Figure 8
Intensity distribution in the focal plane. (a) Upper subplot: horizontal beam profile at 8.2 keV with the diamond phase plate (orange, dashed line) compared with the aberrated (blue, solid line) and ideal (green, dotted line) lens. Lower subplot: horizontal beam profile at 35 keV with the polymer phase plate (orange, dashed line) compared with the aberrated (blue, solid line) and ideal (green, dotted line) lens. (b) Radially integrated intensity distribution at both 8.2 keV (solid lines) and 35 keV (dotted lines), comparing the aberrated lens (blue) with the phase plate corrected (orange) and ideal (green) lens. The dashed horizontal line marks 0.75. |
