Abstract: An optical assembly incorporates a compact and efficient lens for coupling a beam of light from an optical device to an optical fiber. The lens includes a curved reflecting surface and a focusing surface. The lens is positioned to receive and internally reflect the beam of light from the optical device toward the focusing surface. The focusing surface in turn focuses the reflected beam into the end of an optical fiber. The curved surface may include a reflective coating for transmitting a portion of the beam toward a monitoring unit which is used to monitor a parameter of the beam. The optical assembly may further include a platform for supporting the optical device, the lens, the optical fiber and the monitoring unit.

Abstract: A lens driving apparatus includes: a fixed assembly including a base frame; a movable assembly including a lens holder configured to hold a lens unit; at least one set of magnets surrounding the movable assembly; three sets of coils configured to interact with the magnets and drive the movable assembly to move along a first, a second, and a third orthogonal axes; and a spring system attached between the movable assembly and the fixed assembly. The third axis is parallel to an optical axis of the lens unit. The first and second axes are respectively perpendicular to the third axis. The three sets of coils include a set of focusing coils and two sets of side coils. The at least one set of magnets include four magnetic members attached to inside walls of the outer casing, among which each two magnetic members are placed opposing to each other.

Abstract: A compact camera modules has first, second, and third lens groups that move along an optical axis. A stepping motor is centered on the optical axis rather than offset from the optical axis. The motor has two coils that are fixed in place and a shared rotating magnet. The magnet is attached to a rotating guide that has slots to move the first and second lens groups as it rotates. The two coils are alternately energized to rotate the magnet, the rotating guide, and to move the first and second lens groups for zoom. The magnet has alternating thicker and thinner segments of opposite polarity. The thicker segments exert a greater force on an autofocus coil that is energized to move the third lens for the autofocus function. The same shared rotating magnet is used for both zoom and autofocus functions. A more compact design is possible using a shared magnet.

Abstract: A lens actuation device for an optical system includes a housing, a carrier at least partially installed in the housing, and a plurality of transducers arranged around the carrier in the housing. All the transducers are coupled with the mount, and at least one transducer includes at least one magnet and at least one coil. At least one transducer includes at least one yoke. All the transducers when powered on may generate independent or consistent movement to cause the mount to make linear movement, rotation, or both relative to the housing. An optical system adopting the lens actuation device and a camera using the same are also presented. The device of the present invention uses the transducers to drive the carrier, such that the lens set is driven to make linear movement, rotation, or both, thereby achieving the flexible manipulation of the lens.
