Wafer-level lens module with extended depth of field and imaging device including the wafer-level lens module
A wafer-level lens module with an extended depth of field (EDF) and an imaging device including the wafer-level lens module are provided. The wafer-level EDF lens module includes a plurality of wafer-scale lenses stacked with fixed distances therebetween. The plurality of wafer-scale lenses includes an effective lens having a profile which satisfies a corrected optimized aspheric function, wherein a profile of a center region of the effective lens is optimized for an infinity-focused image and a profile of an edge region of the effective lens is optimized for a macro-focused image.
