摘要
A focussed grating device (100) is described comprising a substrate (402) and a grating comprising a plurality of grating features (408) positioned on the substrate (402). The grating features (408) are positioned non-perpendicular to the substrate surface, thereby inducing a first focusing direction. The substrate (402) is curved, thereby inducing a second focusing direction, which is different from the first focusing direction. An X-ray system (300) comprising such a focussed grating device (100) as well as a method for producing such a focussed grating device (100) are also described.
