Large-aperture refractive lenses for momentum-resolved spectroscopy with hard X-rays

Abstract

One-dimensional kinoform and prism refractive lenses with large aperture and high transmittance at 22 keV have been investigated. A 12.0 μm focus size (full width at half-maximum) and an effective aperture of 0.85 mm, at a focal length of 705 mm and 21.747 keV, were achieved. © 2013 International Union of Crystallography Printed in Singapore - all rights reserved.
