A compound refractive lens for focusing high-energy X-rays
- A. Snigirev, V. Kohn, I. Snigireva, B. Lengeler
- Chemistry
- Nature
- 1 November 1996
THE development of techniques for focusing X-rays has occupied physicists for more than a century. Refractive lenses, which are used extensively in visible-light optics, are generally considered… Expand
On the possibilities of x-ray phase contrast microimaging by coherent high-energy synchrotron radiation
- A. Snigirev, I. Snigireva, V. Kohn, S. Kuznetsov, I. Schelokov
- Physics
- 1 December 1995
Coherent properties of the x-ray beam delivered at the ESRF allow the observation of very weak perturbations of the wave front, resulting in the phase contrast. A straightforward experimental setup… Expand
X-ray imaging with submicrometer resolution employing transparent luminescent screens
- A. Koch, C. Raven, P. Spanne, A. Snigirev
- Materials Science
- 1 July 1998
Microimaging techniques with synchrotron radiation demand fast, on-line x-ray detectors with a spatial resolution in the micrometer or submicrometer range. For this task an x-ray detector based on a… Expand
Imaging by parabolic refractive lenses in the hard X-ray range
- B. Lengeler, C. Schroer, +5 authors M. Drakopoulos
- Physics
- 1 November 1999
The manufacture and properties of compound refractive lenses (CRLs) for hard X-rays with parabolic profile are described. These novel lenses can be used up to ∼60 keV. A typical focal length is 1 m.… Expand
X-ray transfocators: focusing devices based on compound refractive lenses

Refractive x-ray lenses
- B. Lengeler, C. Schroer, +6 authors I. Snigireva
- Physics
- 21 May 2005
Parabolic refractive x-ray lenses are novel optical components for the hard x-ray range from about 5 keV to about 120 keV. They are compact, robust, and easy to align and to operate. They can be used… Expand
High energy X-ray microscopy for characterisation of fuel particles
- B. Salbu, T. Krekling, +9 authors V. Kashparov
- Physics
