Figure 2
Top row: measured Ronchigrams with horizontal and vertical gratings, using a CRL (0 mm defocus) on the left side and a ZP (−1.0 mm defocus) on the right. Middle row: simulated Ronchigrams with aberrations. Bottom row: simulated Ronchigrams for perfect aberration-free optics. The cross in the right-hand-side images is the ZP central stop. |
