Abstract

A nanocomposite-ink refractive gradient optic with variable focus optic comprising a first optical-element, a second optical-element, each the optical-elements comprised of a cured nanocomposite-ink wherein the first and second optical-element have a cubic volumetric gradient complex optical index such that when arranged in tandem along an optical axis the optical power varies based on linear translation with respect to another.
