Focusing of X-rays by means of (a) FZP, BFZP in (b) Bragg and (c) Laue diffraction geometries. Φf is the energy flux in the focal peak, Φ0 is the energy flux of radiation incident on the lens, and Φe is the energy flux of the wave package leaving the lens that falls on the focal plane after propagation in a vacuum. |
