Lithium Lens Focuses X-Rays
Mar 1, 2002 — With a little extra care, researchers at the University of Michigan in Ann Arbor, Ecopulse Inc. in Springfield, Va., and the US Army Research Laboratory in Adelphi, Md., have expanded the materials from which a lens can be made. The team has reported the focusing of 10-keV x-rays with a prototype refractive lens constructed of lithium.
