  • Publication number: 20080019656
    Abstract: A device for shifting the imaging axis of a microscope across the endfaces of a multi-fiber connector for inspecting the fiber-optic endfaces through the microscope comprises a supporting body for attaching at one end to the optical tube of a microscope; a pendular arm rotatably mounted to another end of the supporting body; a fitting tip attached to another end of the pendular arm; a bevel wheel fastened to the supporting body; and a torsion spring for pushing the pendular arm against a slanted surface of the bevel wheel. The bevel wheel is adapted to swing the pendular arm relative to the supporting body so that the imaging axis of the microscope is moved relative to the fitting tip to selectively align the imaging axis between adjacent fiber-optic endfaces for inspection.

  • Patent number: 7016565
    Abstract: A micro-optic fiber device is provided with independent counter-bore tubes and coupling tubes serving as couplers for coupling the optical processing elements, micro lenses and the fiber pigtails. The micro-optic fiber device can be built using direct coupling manner, wherein the optical processing element is firstly inserted and fixed in the step groove of the counter-bore tube by applying bonding agent between the outer periphery of the optical processing element and the inner surface of the step groove, and then the counter-bore tube is coupled with the coupling tubes, thus eliminating the need of using bonding agent between the optical processing element and the micro lenses and preventing the bonding agent from diffusing and spreading over the optical path.

  • Patent number: 6853794
    Abstract: An apparatus comprising an acoustically resonant ultrasound launcher is provided for cleaning of optical fiber connectors and other optical fiber parts. The resonant ultrasound launcher is designed to transfer and to focus ultrasonic energy from an ultrasound transducer to a relatively small target area with high intensity. Specially designed fluid flow channels allow this apparatus to efficiently clean optical fiber connectors with an exposed end surface or with an end surface concealed in a connector adapter. Circuitry is provided to automatically track the frequency to enhance the ultrasound generation. Another circuitry is provided to program the sequence of the cleaning process, including washing, rinsing and drying.

  • Patent number: 6836370
    Abstract: An optical collimator is provided for ready fitting to an optical device with precise optical alignment, to obviate the need for adjusting the collimator during assembly to the optical device to compensate for a translational offset and an angular deviation. In an embodiment, the collimator has a sleeve with an outer cylindrical surface that is concentric with the output optical path, which has a translational offset and an angular deviation with respect to the collimator axis. A method is provided for making such a collimator for ready fitting to an optical device with precise optical alignment. In an embodiment, a portion of an outer sleeve of the collimator is removed according to the offset and the deviation to form an outer cylindrical surface that is centered about an axis which coincides with the optical path emanating from the collimator, to allow the collimator to be readily fitted to an optical device.
