Comparison between the coherence and nano-focusing properties of the partially coherent wave propagation through a perfect mirror (two upper panels) and a mirror with the height and slope profiles of Fig. 9[link] (lower panels). The upper and lower left panels show Γ while the upper and lower right panels show γ extracted from Γ by using the normalization factor (Ii)1/2(Ij)1/2 = [\exp[-{{(x_{i}^{2}+x_{j}^{2})}/{4\sigma_{x}^{2}}}]]. The fitting values for the perfect mirror case were [\sigma] = 20.3 ± 0.4 µm and [\xi] = 26.2 ± 0.2 µm, and for the imperfect mirror [\xi] = 26.1 ± 0.7 µm and [\sigma] = 19 ± 1 µm.
