Abstract
An optical-dispersion corrected optical-element with a first and a second surface for imaging equal angle quadrilateral focal plane array (FPA). The optical-dispersion element comprises a first nanocomposite-ink with a first nanofiller dispersed in a cured organic-matrix and a second nanocomposite-ink with a second nanofiller dispersed in the cured organic-matrix. Optical-dispersion of the second nanocomposite-ink is different than optical-dispersion of the first nanocomposite-ink. The distribution of the first nanocomposite-ink and second nanocomposite-ink corrects chromatic aberration and creates a refractive gradient that is non-radially symmetric to correct for an image plane array.
