Single bounce ellipsoidal glass monocapillary condenser for X-ray nano-imaging

•A single bounce ellipsoidal glass monocapillary was designed and fabricated.•The slope error of monocapillary measured by optical equipment was small.•The focal spot size and ring obtained by X-ray test showed that the quality of monocapillary was high.

A single bounce ellipsoidal glass monocapillary was designed and fabricated and its performance was measured by both an optical measurement and an X-ray test. This monocapillary had a slope error of 17 μrad. The images of the focal spot and the far-field pattern recorded by a CCD detector showed that this fabricated monocapillary had high quality and satisfied the requirement of the designed data for X-ray nano-imaging.
