(a) Intensity on the optical axis calculated for a clessidra lens for NT = 31, m = 1, energy = 8 keV, h = 25.67 µm, δ = 4 × 10−6, m0 = 1 and b = mλ/δ, as a function of a = q/f. Ideal case, continuous curve; energy detuning, dashed curve; tips of size w, short-dashed curve; compensating w with detuning, long-dashed curve; compensating w with a larger central gap, dotted curve. (b) Intensity at the focus distance calculated for a clessidra lens as a function of x/h. The parameters are the same as in (a).
