  • Actuator with multipolar magnet structure
    Patent number: 11824417
    Abstract: An actuator with a multipolar magnet structure includes a carrier configured so that a lens is loaded thereon, the carrier being configured to linearly move along an optical axis direction, a housing configured to accommodate the carrier, a coil unit provided in the housing and having an n number of coils arranged along the optical axis direction in the same side of the housing, where n is a natural number of 2 or above, and a magnet mounted to the same side of the carrier to face the coil unit, the magnet having an n+1 number of magnetic poles facing the coil unit.

  • Apparatus for supporting optical reflector
    Patent number: 10571093
    Abstract: An apparatus for supporting an optical reflector to change a path of light and introduce the light to a lens includes an inclined unit configured to support a reflective surface of the optical reflector; a guide wall formed at a side of the inclined unit to support a side surface of the optical reflector; a guide opening formed in the guide wall; and a support member made of a material different from the material of the optical reflector and inserted into the guide opening so that an inner surface of the support member is fixedly coupled to the side surface of the optical reflector.
