2D parabolic X-ray compound refractive lens was manufactured by laser micro-machining of a single-crystal diamond.
The lens consists of parabolic half lenses with apertures of 1 mm and parabola apex radii of 200 μm. It has been tested at
the synchrotron undulator source (ID06, ESRF) and at a laboratory setup using MetalJet X-ray tube with a liquid-gallium
jet as the anode. X-ray imaging and focusing modes were used. Unique optical and thermal properties of singlecrystalline
diamond lenses allow them to be applied as focusing, imaging and beam-conditioning elements at high-heat
flux beams of today and future X-ray sources.
