Abstract
Several optical configurations aiming to create images of sub-millimetre objects with magnification from 1 to 100 have been experimentally tested at the ESRF BM5 beamline. A Kirkpatrick-Baez (KB) System is used for focusing the beam into a 30 microns spot and then direct projection images are recorded. Some results using a spherical crystal downstream from the KB System are presented. The possibility to focus the synchrotron beam into a 40 microns spot using an spherical crystal in quasi-normal incidence is demonstrated and its use for projection microscopy is discussed.
