Figure 5
Comparison of the vignetting function when using lens-by-lens attenuation and using a combination of two effective apertures, one in the sample plane and one at the exit plane of the CRL. The intensity relative to the object plane is shown in (a) and the corresponding error in (b). The phase and phase error are shown in (c) and (d), respectively. Simulation details: 2D wavefront, 1000 × 1000 pixels, 1 µm pixel size; see also `Example_Figure_5.m' of Pedersen (2017BB3). The plots are cross sections perpendicular to the optical axis.
