Embedded lens for achromatic wafer-level optical module and methods of forming the same

A wafer-level optical lens module including one or more embedded lenses and two outer lenses on an outer side of two outermost glass wafers. The embedded lenses may be formed of air or of any material with desired refractive index and dispersion characteristics. The outer lenses may be formed of any...

Summary:A wafer-level optical lens module including one or more embedded lenses and two outer lenses on an outer side of two outermost glass wafers. The embedded lenses may be formed of air or of any material with desired refractive index and dispersion characteristics. The outer lenses may be formed of any material with desired refractive index and dispersion characteristics. This arrangement, with various lenses of the optical module having different refractive indices and dispersions, allows for the formation of a wafer-level optical lens system which corrects for chromatic aberration and astigmatism.
