Refractive Optics
 Refractive optical elements are lenses that bend light through refraction. Instead of conventional fabrication processes in which lenses are fabricated either through grinding individual elements or a molding process in which single or small numbers of elements with each cycle of a machine, Tessera's refractive optics are made on 100mm or 150mm wafers where thousands of lenses are simultaneously formed on the surface. Refractive lenses are formed on both the front and back surface with submicron precision. Some methods of manufacturing include direct etch in to the substrate and replication of the lenses in to a polymer layer located on the wafer surface.
