  • Patent number: 8585220
    Abstract: Provided is a method of producing an optical element, including: forming a frame portion on a substrate and forming a structural body in a space portion surrounded by the frame portion to thereby form a first optical member; disposing a second optical member on the first optical member in a reduced pressure environment to form an optical element in which the space portion is sealed in a pressure-reduced state; and exposing the optical element to the atmosphere to thereby bring the structural body and the second optical member into close contact with each other by a differential pressure between the atmosphere and the space portion sealed in the pressure-reduced state. Accordingly, it is possible to, when the optical element is bonded, suppress damage to the optical element during the bonding and further improve the function and strength of the optical element without use of an adhesive.

  • Patent number: 8545114
    Abstract: A camera module includes a lens system, an image sensor, and an actuator. The actuator is fixed relative to the image sensor, and the actuator moves the lens system relative to the image sensor to achieve focus. Components that move relative to each other result in gaps or spaces between the components, an in particular there is a gap between the lens system and the actuator. Such a gap provides a traveling path for foreign material, or particulates, to enter the camera module and reach the image sensor, or other intermediate optical components between the lens system and the image sensor. A camera contamination reduction apparatus is implemented as a protective membrane that prevents foreign material from reaching the internal optical components through the traveling path.

  • Patent number: 8548318
    Abstract: A dust-screening member is shaped like a plate as a whole, and has at least one side that is symmetric with respect to a virtual axis on a surface of the member. A vibrating member is adjacent to one side of the dust-screening member, arranged on the surface along the one side, and configured to produce, at the surface, vibration having a vibrational amplitude perpendicular to the surface. A drive unit is configured to drive the vibrating member to produce the vibration on the surface, such that peak ridges of the vibration form a closed loop and an area including a center of the closed loop is surrounded by a node area having almost no vibrational amplitude. When a thickness of the dust-screening member is assumed to be tg and a thickness of the vibrating member is assumed to be tp, tg/tp has a dimension of 0.8.

  • Publication number: 20130114141
    Abstract: Techniques and architecture are disclosed for implementing an optical dome bezel to interface an optical dome/window and a housing of differing coefficients of thermal expansion (CTEs), In some embodiments, the bezel may comprise a material (e.g., Ti-6Al-4V) that is CTE-matched to the optical dome material (e.g., silicon, germanium, sapphire, ALON), thereby mitigating temperature effects on system performance. In some embodiments, the bezel may include a radially compliant flexure feature (e.g., flexure blades, spring-form S-channels), which mitigates physical stress effects (e.g., vibration, thermal expansion/contraction, etc.) on system performance. In some embodiments, the bezel may include an integral environmental sealing feature (e.g., O-ring gaskets), which protects internal optics/electronics from external environmental hazards (e.g., moisture, corrosive substances, particulates, debris).

  • Publication number: 20120281282
    Abstract: The imaging apparatus holds an imaging element that converts a subject image that has been formed by an imaging optical system to an electric signal by a holding member. An optical member is disposed more toward the subject side than the imaging element and is installed on the holding member. A sealing member that is formed by an elastic material encloses the light receiving surface of the imaging element as a countermeasure for dust protection. A position restricting member provided on the sealing member carries out positioning by being inserted between the outer peripheral edge portion of the optical member and the holding member in a direction perpendicular to the optical axis of the imaging optical system.

  • Patent number: 8197073
    Abstract: A mirror hangs from a transparent enclosure which may surround a shower, a bathtub, or other bathing area. The mirror may be in a position that avoids condensation on the surface of the mirror from steam emitted from the transparent enclosure. The mirror may also be in a position so that the mirror reflects light into the enclosure. An individual in the bathing area may use the mirror from inside the transparent enclosure without the mirror fogging, which is a common problem associated with using mirrors in a bathing area. The mirror may hang from the outside of the transparent enclosure and optionally includes a sealing element or a frame surrounding the reflective element to further avoid contact with steam.

  • Publication number: 20120113513
    Abstract: Apparatus and methods for self-cleaning of optical elements in sealed environments over a wide range of operating optical frequencies prevent long-term power degradation by introducing low-pressure backfill of a reactive gas such as oxygen into a vacuum chamber containing the optical elements. The backfill pressure is preferably between 10?4 torr and 10 torr, and generally between 0.1 torr and 2 torr at room temperature. The vacuum chamber may be continuously evacuated and backfilled, or may be sealed after evacuation and backfill is performed.
