Figure 9.

(a) Fraunhofer diffraction pattern of the 2DWG-1, pre-focused by KB mirrors, at 15.0 keV (logarithmic scale, scalebar 0.02 Å⁻¹, 100 s dwell time). (b) WG near-field distribution in the effective confocal plane of the 2DWG-1, reconstructed using the ER algorithm (logarithmic scale, scalebar 20 nm). (c) Horizontal (top) and vertical (bottom) linescans (linear scale) of the reconstruction in (b) along with Gaussian fits yielding a width of 10.0 × 9.8 nm. (d) Far-field pattern of the 2DWG-2, measured at 13.8 keV (logarithmic scale, scalebar 0.02 Å⁻¹, 1 s dwell time). (e) Reconstructed near-field of the 2DWG-2 (logarithmic scale, scalebar 20 nm). (f) Line profiles in the horizontal (top) and vertical (bottom) direction (linear scale), along with Gaussian fits yielding a width of 10.7 × 11.4 nm.
