Figure 8
Comparison of the measured grating efficiencies for a photon energy of 4 keV (λ = 0.307 nm) for different orders (zeroth to third) in the conical diffraction scheme as measured by Jark & Eichert (2015) with the calculations using the rigorous approach accounting for the real grating profile (solid line). The prediction by the scalar theory is shown by the dashed line. |
