Abstract:
Ultra thin Fresnel lenses and methods of forming the same are described herein. An optical element comprising an ultra thin Fresnel lens includes a plurality of Fresnel elements formed on a surface of a substrate. Each of the plurality of Fresnel surface elements has an angled facet portion and a shallow or substantially horizontal portion. The Fresnel surface elements can be formed, for example, by a hot stamp or cold transfer method.
