摘要

We present an innovative X-ray telescope design for diffraction-limited imaging on the mas scale. The long focal distance scheme is based on dispersion-corrected Fresnel lenses made of Li and Be. Annular apertures with an outer diameter of 3.5 m permit simultaneously focused X-rays in two energy bands around 5 and 10 keV. Concentrated to focal spot sizes of ～ 1 mm, a photon throughput of～1400 cm~2 keV is achieved in the soft and hard band as well. With its partial spectroscopic capability, the device might be preferably suited for measurements of hardness ratios in X-ray emitting coronae of nearby stars and even disc-to-jet conversion mechanisms within AGN.
