Fresnel lens with organic solid crystals

Abstract

A Fresnel lens includes a lens body having a structured surface with a plurality of facets, where the lens body includes an organic solid crystal having mutually-orthogonal refractive indices, nx, ny, nz. In a related vein, an apparatus includes a display and an optical configuration configured to receive display light from the display, where (a) the optical configuration includes a Fresnel lens assembly having a Fresnel lens and a Pancharatnam-Berry Phase lens overlying the Fresnel lens, (b) the Fresnel lens includes a lens body having a structured surface including a plurality of facets, and (c) the lens body includes an organic solid crystal.
