In this work, we present a new generation of ultra-compact and high-vacuum cooled transfocators based on refractive lenses for the collimation, transport, and focusing of hard X-ray radiation. A transfocator is an optical device capable of changing the position of the focus depending on the number of refractive X‑ray lenses that are exposed along the X-ray optical path. The design features of this device make it possible to control individual optical elements independently of each other, providing more flexible focal-length adjustment for a wide range of applications. The small overall dimensions and light weight of the devices make it possible to integrate them into any synchrotron-radiation station.
