Abstract
A reflective lens with at least one curved surface formed of polycrystalline material. In one embodiment, a lens structure includes a substrate having a surface of predetermined curvature and a film formed along a surface of the substrate with multiple individual members each having at least one similar orientation relative to the portion of the substrate surface adjacent the member such that collectively the members provide predictable angles for diffraction of x-rays generated from a common source. A system is also provided for performing an operation with x-rays. In one embodiment, a system includes a source for generating the x-rays, a polycrystalline surface region having crystal spacing suitable for reflecting a plurality of x-rays at the same Bragg angle along the region, and transmitting the reflected x-rays to a reference position. An associated method includes providing x-rays to polycrystalline surface region having crystal spacings suitable for reflecting a plurality of x-rays at the same Bragg angle along the region, transmitting the reflected x-rays to a reference position and positioning a sample between the surface region and the reference position so that the x-ray…
