The first visible-light Luneburg lens - a previously impossible-to-fabricate spherical lens with unique focusing properties

Caption

Illinois researchers developed a spherical lens that allows light coming into the lens from any direction to be focused into a very small spot on the surface of the lens exactly opposite the input direction. This is the first time such a lens has been made for visible light.
