Abstract :
Silicon planar parabolic refractive lenses including lenses with minimized absorption are created by the microfabrication technique. Focusing properties of the lenses were studied with synchrotron radiation in the X-ray energy 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 lenses at 8 keV and in the X-ray energy range over 15 keV it exceeds 90%. Spectral and heatload properties of lenses with minimized absorption are discussed in detail.
