Abstract: A device for filtering a ray bundle of electromagnetic radiation, particularly an X-ray bundle has different filter stages, produced by multiple filters that can be adjusted into the ray bundle, a drive for moving the filters, and separate arms for moving each of the filters. The respective first ends of the arms engage at the appertaining filter and the respective other ends thereof are chargeable with a force generated by the drive. Dependent on the motion of the drive, each of the filters can either be set into the beam path by charging the appertaining arm with an actuating force or can be retrieved from the ray bundle by charging the arm with a restoring force. A dog driven by the drive is able to be brought into contact with two detents respectively present at each of the arms. An IN detent is provided for charging the arm with the actuating force and an OUT detent is provided for charging the arm with the restoring force.

Abstract: An optical coupler 10 comprising at least three fibres 12, 14 and 16, portions of the fibres being fused to each other to form a coupling region 30 operable to couple light therebetween. At least two of the fibres have inputs 18 and/or 20 and/or 22 and at least two of the fibres have outputs 24 and/or 26 and/or 28. In use, on illumination of at least two of the inputs light intensity is emitted from a plurality of the outputs having a substantially asymmetric phase relationship, such as, for example, a quadrature phase relationship between two of the outputs. The invention also provides for methods of making such a device.

Abstract: An optical fiber in which propagation is monomode propagation when incorporated into a cable has, at a wavelength of 1 550 nm, a chromatic dispersion from 3 ps/(nm.km) to 14 ps/(nm.km) and an absolute value of chromatic dispersion slope less than 0.014 ps/(nm2.km), and, at a wavelength of 1 625 nm, bending losses measured for a 10 mm radius less than 400 dB/m. The proposed criteria allow use of the fiber over a wide band of wavelengths in a wavelength division multiplex transmission system. The low chromatic dispersion slope simplifies the management of chromatic dispersion in the transmission system.

Abstract: An optical collimator (10) includes an input optical fiber (11), an output optical fiber (12), a ferrule (13) receiving the input optical fiber and the output optical fiber therein, a molding lens (14), and a filter (15). The molding lens includes a solid cylindrical main body (141), and a pair of cylindrical protrusions (142, 143) respectively extending from opposite ends of the main body. The main body includes an inmost oblique end face (18), and an opposite aspherical end face (19). The ferrule is received in one protrusion and opposes the oblique end face. The filter is received in the other protrusion and opposes the aspherical end face.

Abstract: A method and apparatus for performing interferometric measurement/testing of flying heights of read-write head sliders utilizing an improved rotating disk, the disk having a central opening for use with a spindle for rotation about a central axis, the disk comprising: a substrate comprised of a light transmissive material and including a pair of opposed, smooth, major surfaces; and a wear-resistant, protective overcoat layer on one of the major surfaces for improving the tribological properties thereof; wherein the optical properties of the one surface of the disk are optimized for enhancing the sensitivity of the interferometric measurement/testing by increasing the intensity of reflected light received by a detector of the apparatus.

Abstract: A distribution terminal is provided for interconnecting one or more fiber optic drop cables with at least one fiber optic distribution cable at a convenient access point in a telecommunications network. The terminal comprises a base and a cover adapted to be opened and closed on the base. The base defines an interior cavity having a lower fiber management area for accessing the distribution cable and an upper fiber management area for accessing the drop cables. The upper fiber management area includes a transition panel that is movable relative to the base to provide access to the lower fiber management area. Thus, both the lower fiber management area and the upper fiber management area are easily and readily accessible to a field technician initially installing the terminal and subsequently reconfiguring the optical fiber connections within the terminal at the access point.
