Diffractive X-ray LensesX-rays are used in a wide range of experiments to investigate the structure of matter. They give the ability to penetrate comparatively thick samples, and give information on the elemental and even chemical composition. Moreover, and the short wavelength carries the potential of excellent spatial resolution down to the atomic scale. In practice, the spatial resolution of x-ray probes and x-ray microscopes are limited by the quality of the available x-ray optics.
The X-Ray Optics and Applications group is specialized on pushing the limits of diffractive x-ray optics, regarding resolution and efficiency. We collaborate with many research groups at synchrotron end stations to provide optimized, custom-made devices for optimum performance, covering a wide photon energy range from below 100 eV to beyond 10 keV. Moreover we develop novel optical schemes and application areas, such as advanced Zernike phase contrast imaging, coherent diffraction imaging, or devices for experiments at X-FEL sources.
