The concept of an undulator-based beamline for refractive lenses-based hard X-ray coherent nanoscopy and nanotomography at a fourth-generation synchrotron radiation source is presented. We describe experimental scenarios and optics operational modes that allow varying the scale of the sample area under study in the range of ~0.1-100 μm and achieving spatial resolution down to ~10 nm. Solutions to eliminate the disadvantages of beryllium lenses are proposed. Keywords: X-ray microscopy, coherent imaging, synchrotron radiation, X-ray refractive optics.
