Abstract
An optical-dispersion corrected optical-element, the optical-element comprising a first nanocomposite-ink, the first nanocomposite-ink comprising nanofillers dispersed in a cured organic-matrix, a second nanocomposite-ink, the second nanocomposite-ink comprising the nanofillers dispersed in a the cured organic-matrix, optical-dispersion of the second nanocomposite-ink different than optical-dispersion of the first nanocomposite-ink, wherein the distribution of the first nanocomposite-ink and the second nanocomposite-ink result in optical-dispersion refractive-gradients, where the refractive-gradients correct chromatic aberration.
