  • Publication number: 20100073781
    Abstract: The present invention provides a manufacturing method for a wafer lens module including the steps of providing a plastic material with high thermal resistance, wherein the high temperature plastic material can be used at a reflow temperature above 250° C.; and forming the high temperature plastic material into a wafer lens module integrally. The method can form an integrated wafer lens module and simplify the manufacturing procedures. Furthermore, a wafer lens unit formed by stacking another wafer lens module on the wafer lens module manufactured by the method can have improved optical image quality.

  • Publication number: 20090195897
    Abstract: A lens module includes a lens barrel, a lens, a sensing element, and an electromagnetic shield. The lens barrel defines a receiving space. The lens is mounted in the receiving space. The sensing element is covered by the lens barrel, is disposed below the lens, and is spaced apart from the lens. The sensing element includes a top face, a bottom face, a side face extending between the top and bottom faces, a plurality of first conductors mounted on the bottom face, at least one second conductor mounted on one of the top, bottom, and side faces, and a grounding element having one end connected to one of the first conductors and the other end connected to the second conductor. The electromagnetic shield is coupled to the lens barrel and includes a grounding portion electrically connected to the second conductor.

  • Patent number: 7466492
    Abstract: An image capturing device includes a base, a lens module, and an electrically conducting mechanism. The lens module includes a fixed lens set and a liquid lens disposed respectively in an adjusting seat with first and second through holes. The liquid lens has first and second electrode portions. The conducting mechanism includes first and second conducting members disposed respectively on outer and inner surfaces of a surrounding wall of the base, a third conducting member abutting against the first electrode portion and extending through the first through hole to contact the first conducting member, and a fourth conducting member abutting against the second electrode portion and extending through the second through hole to contact the second conducting member. When the adjusting seat is rotated relative to the base, the first and second electrode portions of the liquid lens are respectively and electrically connected to the first and second conducting members.
