Figure 6
Residual wavefield error in the plane of the phase plate. (a) Wavefield error in the plane located 10.5 mm downstream of the lens exit aperture of 50 Be CRLs at 8.2 keV with (right) and without (left) corrective phase plate. (b) Wavefield error in the plane located 20 mm downstream of the lens exit aperture of 149 Be CRL at 35 keV with (right) and without (left) corrective phase plate. The scale bar in both figures represents 100 µm. |
