Focusing performance for lens stacks with #!N = 20, 40 and 60 lenses as a function of lens length L over focal length f. Solid lines mark the best achievable performance of an aberration-free lens. Dotted lines represent lenses affected by spherical aberration. The triangle, circle and square show results with phase plates designed for #!E = 10 keV, 8.5 keV and 7 keV, respectively. Dashed lines indicate the performance if the phase plate is used at differing energies than the design one. The dash-dotted line indicates the performance of a phase plate designed for #!E = 7 keV that is positioned further downstream for higher energies according to the change in focal length.
