Abstract
Providing for a wafer level optical system employing composite lenses is disclosed herein. Conventional focus lens assemblies require three or more lenses. By way of example, two composite lenses can be used to reduce the cost of a wafer-level camera. In some aspects, the composite lenses can be aspheric and can employ a broader variety of wafer materials than earlier designs that only operated in narrow ranges of refractive indices and Abbe numbers.
