OPTICAL UNIT, METHOD OF PRODUCING THE SAME, AND IMAGE PICKUP APPARATUS

摘要

An optical unit includes a plurality of lenses arranged along an optical path from an object side toward an image side, the plurality of lenses including at least one lens including an image side surface and an object side surface, one of which is formed to be an aspheric surface at wafer level, the aspheric surface of the at least one lens being formed to serve as one of an aperture stop surface having an aperture stop function and a light-shielding surface having a light-shielding function.
