Patent ID: 7742574

Claim:
An x-ray optics device arrangement, wherein said x-ray optics device arrangement is arranged for x-rays of energies exceeding 10 keV, and comprising a plurality of individual three-dimensional prism structures, each having a multitude of prisms for both refraction and diffraction of incoming x-rays to shape the x-ray flux, said multitude of prisms being arranged in at least one layer around an axis of symmetry, corresponding to an optical axis for incoming x-rays, to enable a two-dimensional focusing effect, wherein a number of independent discs, each disc having at least one layer of at least part of a prism, are provided in parallel on a common substrate and a number of such substrates are stacked in alignment to form said plurality of three-dimensional prism structures, such that each three-dimensional prism structure is formed as a rotationally symmetric or near symmetric assembly of a plurality of discs stacked along the optical axis.
