  • Optical module with a lens encapsulated within sealant and method for manufacturing the same
    Patent number: 8823150
    Abstract: A method to manufacture an optical module is disclosed, wherein the optical module has an optically active device on a lead frame and a lens co-molded with the active device and the lead frame by a transparent resin as positioning the lens with respect to the lead frame. The molding die of the present invention has a positioning pin to support the lens during the molding. Because the lead frame is aligned with the molding die, the precise alignment between the active device on the lead frame and the lens is not spoiled during the molding.
