X-Ray Optics and Nanoimaging
Our research
Senior scientist: Ulrich Vogt
X-ray nanoimaging is a rapidly evolving frontier at synchrotron radiation and X-ray free-electron laser facilities worldwide. By focusing X-ray radiation to spot sizes as small as 10–100 nanometers, this cutting-edge technology enables groundbreaking research across numerous scientific fields.
The unique capability of X-ray nano imaging lies in its ability to conduct direct in-situ and in-operando experiments, even in extreme physical environments. This technology provides an unparalleled link between a material's structure and its physical properties, offering insights that were previously inaccessible.
We design and manufacture advanced diffractive zone plate optics that achieve diffraction-limited resolution in the 10–100 nm range, tailored for X-ray nano imaging in both the soft and hard X-ray spectrum. In collaboration with Lund University, we have developed the NanoMAX beamline and a zone-plate-based X-ray microscope at the Swedish synchrotron source MAX IV.
Our long-term goal is to enable 3D X-ray imaging experiments with a resolution as fine as 10 nanometers.
