Broadband ptychography using curved wavefront illumination
Daniel S. Penagos Molina, Lars Loetgering, Wilhelm Eschen +2
We examine the interplay between spectral bandwidth and illumination curvature in ptychography. By tailoring the divergence of the illumination, broader spectral bandwidths can be…

Material-specific high-resolution table-top extreme ultraviolet microscopy
Wilhelm Eschen, Lars Loetgering, Vittoria Schuster +9
Microscopy with extreme ultraviolet (EUV) radiation holds promise for high-resolution imaging with excellent material contrast, due to the short wavelength and numerous element-spe…
