Scientists develop spectacles for X-ray lasers

(Deutsches Elektronen-Synchrotron DESY) An international team of scientists has tailored special X-ray glasses to concentrate the beam of an X-ray laser stronger than ever before. The individually produced corrective lens eliminates the inevitable defects of an X-ray optics stack almost completely and concentrates three quarters of the X-ray beam to a spot with 250 nanometers diameter, closely approaching the theoretical limit. The team surrounding DESY lead scientist Christian Schroer presents
