REFRACTING X-RAY LENS Russian patent published in 2015 - IPC G21K1/06 G02B3/08 

FIELD: physics, optics.

SUBSTANCE: refracting X-ray lens consists of separate focusing elements in the form of triangular prisms arranged into rows. The geometric dimensions, vertex angle and number of elements in each row, as well as the material from which the focusing elements are made vary depending on the selected photon energy in the range from soft X-rays to gamma-rays. The number of focusing elements in different rows is determined by a set of given energies. Each selected energy can match one to several rows of focusing elements. Focusing elements of each row can be made in the form of both right and oblique prisms of different size, with a different vertex angle and with flat or parabolic lateral sides. A beam can be focused in the form of a line or point.

EFFECT: concentrating radiation in a given energy range at a given distance from the lens.
