| 主权项 | 1. An optical unit, comprising: 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 having an image side surface and an object side surface, one of which is configured to be an aspheric surface at wafer level, the aspheric surface of the at least one lens being configured to serve as one of an aperture stop surface having an aperture stop function and a light-shielding surface having a light-shielding function, wherein an infrared cut filter is formed on the aspheric surface of the at least one lens, the aspheric surface being configured to serve as the light-shielding surface. | ||
