Abstract: A wafer-level method for manufacturing yardless lenses includes (a) depositing light-curable lens resin between a mold and a first side of a transparent substrate, wherein the first side of the transparent substrate has an opaque coating with a plurality of apertures respectively aligned with a plurality of lens-shaped recesses of the mold, and (b) exposing a second side of the transparent substrate, facing away from the first side, to light, thereby illuminating portions of the light-curable lens resin aligned with the plurality of apertures to form a respective plurality of yardless lenses.
