Abstract:
According to embodiments of the present invention, a lens comprising a refractive index profile configured such that rays of light propagating in the lens form an at least substantially plane wavefront at an at least substantially vertical plane of the lens, is provided. The profile is configured to vary in an at least substantially bell curve shape along a radial direction of the lens. The lens includes a plurality of layers configured to generate the profile, wherein each layer of the plurality of layers comprises at least a first film and a second film arranged one above the other.
