Abstract
Silicon planar parabolic refractive lenses including lenses with minimized absorption are created by the microfabrication technique. Focusing properti es of the lenses were studied with synchrotron radiation in the X-ray energ y range of 8-25 keV at the ESRF. The intensity transmission of a lens with minimized absorption is two times greater than that of simple parabolic len ses at 8 keV and in the X-ray energy range over 15 keV it exceeds 90%. Spec tral and heatload properties of lenses with minimized absorption are discus sed in detail. (C) 2001 Elsevier Science B.V. All rights reserved.
