FIELD: optics.
SUBSTANCE: use: for X-ray microscopy, microtomography, spectroscopy, fluorescence spectrometry. Summary of invention is in the fact that X-ray lens made from polymer material includes at least one working surface made in form of a paraboloid of revolution with radius of curvature at paraboloid top to 0.4 mcm.
EFFECT: technical result is reduction of focal length of X-ray lens, as well as reduced side effects of X-ray radiation.
