With a parabolic X-ray capillary it is possible to focus a parallel beam into a small spot or to parallelise a divergent beam from an X-ray source placed at the focal point. A parabolic X-ray monocapillary is an imaging single-bounce system. The spot size is not only determined by the manufacturing precision of the optics but also by the properties of the X-ray source.
