Abstract
A nanocomposite optical-element comprising a first surface, a second surface, and a nanocomposite between the first and the second surface. The nanocomposite comprising of a plurality of refractive-gradients, the plurality of refractive-gradients comprising one or more nanofillers dispersed in a cured organic-matrix. The nanofillers concentration variation determining the plurality of refractive-gradient profiles such that a profile discontinuity exists between any of the plurality of refractive-gradients that are adjacent.
