  • Patent number: 10156442
    Abstract: A Fabry-Perot sensor for measuring an inclination. The sensor is fixed on a static detected object, where a mass block is flexibly connected to a top plate, thus the line between the center of gravity of the mass block and the connecting point on the top plate is perpendicular to the horizontal plane. This creates a Fabry-Perot cavity between a reflecting surface disposed at one end of the mass block and the end of an optic fiber. When the detected object is tilted, the line between the center of gravity of the mass block and its connecting point on the top plate remains perpendicular and the F-P cavity length will have a variation in length. The change of cavity length is measured in accordance with the Fabry-Perot principle, thereby the tilting angle, which is the inclination of the detected object, of the mass block is measured.

  • Patent number: 10073218
    Abstract: Double-clad optical fibers with polymer outer coatings are used in fiber amplifiers and fiber lasers to guide and amplify light. As the optical power increases, the optical fibers must dissipate more heat. Unfortunately, it is difficult to dissipate heat through a polymer cladding, especially at high altitude, without introducing phase noise in the optical signal. To overcome this problem, the inventors have realized metallized polymer-clad optical fibers with superior heat dissipation characteristics than conventional polymer-clad optical fibers. An example metallized polymer-clad optical fiber includes a thin chrome layer that is vacuum-deposited onto the polymer cladding at low temperature, then electroplated with a thicker copper layer. In operation, the copper layer dissipates heat from within the fiber's core and claddings via a heatsink, enabling the fiber to guide and amplify high-power optical signals at high altitude.

  • Patent number: 8982486
    Abstract: An image pickup lens unit, in which a holder body and a cover can be easily connected together, without additional components and a resin flow path for the connection. A lens 10 is positioned in a first holder member 20 which remains in a mold. A second holder member 30 for preventing the lens 10 from falling off is molded such that it is welded to the first holder member having the lens 10 positioned therein. This facilitates molding of the second holder member 30 and joining of the second holder member 30 to the first holder member 20 at the same time. Since there is no need to provide a resin flow path for joining the first holder member 20 and the second holder member 30 together, the image pickup lens unit can be made small in size.

  • Patent number: 8976448
    Abstract: A method of producing an optical film laminate includes: stretching and dyeing a laminate including a resin substrate and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate to produce a polarizing film on the resin substrate; laminating a first protective film on the polarizing film on an opposite side to the resin substrate; and peeling the resin substrate, followed by laminating a second protective film on the polarizing film on a side from which the resin substrate has been peeled. The first protective film is a protective film to be placed on an optical cell side when the optical film laminate is attached to the optical cell, the second protective film is a protective film to be placed on an opposite side to the optical cell when the optical film laminate is attached to the optical cell.

  • Patent number: 8944615
    Abstract: A method of manufacturing a projection objective (22) of a microlithographic projection exposure apparatus (10). The projection objective (22) comprises at least one mirror (M1 to M6) that each have a mirror support (241 to 246) and a reflective coating (26) applied thereon. First imaging aberrations of a pre-assembled projection objective are measured. Before the coating (26) is applied, the mirror supports (241 to 246) are provided with a desired surface deformation (34). If the mirrors (M1 to M6) are not reflective for projection light without the coating (26), measuring light is used that has another wavelength. Alternatively, two identical mirror supports (246) may be provided. One support having a reflective coating is part of the pre-assembled projection objective whose imaging aberrations are measured. The other support is provided with surface deformations before coating and mounting the support into the objective.

  • Patent number: 8908282
    Abstract: This invention provides a plastic optical lens having a sprue gate plane. An average height of the portion defined by the width of the sprue gate plane is larger than at least one portion outside of a width of the sprue gate plane of any annular cross-section centering an optical axis between an optical effective diameter region and the sprue gate plane. The plastic optical lens is formed by an injection-molding method that employs a mold comprising an inlet channel arranged between the optical effective diameter region and the sprue gate plane. The inlet channel provides a shortcut that facilitates the molten plastics to flow to the optical effective diameter region as early as possible during the lens molding process, thereby avoiding the formation of a void or a welding line in the optical effective diameter region. Consequently, the production yield for the optical lens can be improved.
