Hard X-ray full field microscopy and magnifying microtomography using compound refractive lenses

For hard X-rays, parabolic compound refractive lenses (PCRLs) are genuine imaging devices like glass lenses for visible light. Based on these new lenses, a hard X-ray full field microscope has been constructed that is ideally suited to image the interior of opaque samples with a minimum of sample preparation. As a result of a large depth of field, CRL micrographs are sharp projection images of most samples. To obtain 3D information about a sample, tomographic techniques are combined with magnified imaging. # 2001 Elsevier Science B.V. All rights reserved. PACS: 07.85.T; 41.50
