  • Patent number: 11693149
    Abstract: A method for forming a molded proximity sensor with an optical resin lens and the structure formed thereby. A light sensor chip is placed on a substrate, such as a printed circuit board, and a diode, such as a laser diode, is positioned on top of the light sensor chip and electrically connected to a bonding pad on the light sensor chip. Transparent, optical resin in liquid form is applied as a drop over the light sensor array on the light sensor chip as well as over the light-emitting diode. After the optical resin is cured, a molding compound is applied to an entire assembly, after which the assembly is polished to expose the lenses and have a top surface flush with the top surface of the molding compound.

  • Patent number: 7978425
    Abstract: A lens barrel is mated with a lens mount through use of a screw thread whereby relative rotation adjusts lens focus. The lens barrel and lens mount are additionally provided with an interengaging formation that is interposed between an optical axis of the lens barrel and the screw thread. This formation provides a cylindrical sliding contact which isolates any particles produced by operation of the screw thread from reaching the optical components at or near the optical axis.

  • Patent number: 7834311
    Abstract: A lens assembly for an imaging device includes a lens for focusing external radiation towards an image sensor of the imaging device. A mounting member is between the lens and the image sensor so that the lens is spaced a set distance from the image sensor. An adjustment member varies position of the mounting member relative to the image sensor so that the set distance is varied.
