Abstract: To ensure laser safety, also in the case of a largest possible coupled optical power, during the direct optical coupling of a light-emitted component to an optical waveguide, an optical system includes coupling the light through a fiber end configured as a multimode step index optical waveguide having a numeric aperture larger than the half-width value of the angular distribution of the radiation emitted from the radiation source. To distribute the radiation fed into the actual optical waveguide over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected such that the coupled light beams are inclined in relation to the geometric axis of the optical core of the fiber end at a defined angle.

Optical coupling paths (8, 9) run via a coupling device (6) between the connections (12, 14) and the respectively assigned optically active zones (1a, 2a) In order in the case of a very tight spacing (a) to permit a favorable crosstalk response and a cost effective design, the coupling paths (8, 9) run in such a way that the spacing (A) between two optically active zones (1a, 2a) is greater than the spacing (a).

Abstract: A component contains a first array with a plurality of electro-optical converters for electro-optically converting a first light wavelength. Each of the electro-optical converters is optically coupled to a respective assigned wave guide. The aim of the invention is to increase the transmission capacity of such a component. To this end, a second row with additional electro-optical converters is provided which is configured to convert a second light wavelength that is different from the first light wavelength. One of these additional electro-optical converters each is optically coupled to one of the plurality of wave guides.

Abstract: The optical transmission device comprises a transmitter which emits radiation vertically with respect to a covering surface. A reflection surface reflects a portion of the emitted radiation back onto an optically sensitive reception zone of a monitor receiver which is disposed on the same side as the transmitter. An intermediate body with a reflecting circumferential surface is disposed between the reflection surface and the reception zone. At least a portion of the reflected radiation passes from the circumferential surface to the reception zone, which significantly increases the yield of the reflected portion used for monitoring purposes.

Abstract: An extraction apparatus for heart pacemaker electrodes or defibrillator electrodes has an anchoring part which can be deformed using an actuating device from a displacement configuration into an expanded locking configuration. The anchoring part has a tube section with several wall cut-outs, which are offset in the axial direction and between which guide rings remain, which are connected by trough-shaped cross members. By exerting a tensile force on a control wire using the actuating device, the tube section is compressed and the trough-shaped cross members are deformed radially, so that they attain engagement with the inner lumen of the spiral helix of a heart pacemaker electrode cable or defibrillator electrode cable and, as a result of a spiral offset, bring about a positive locking, which permits high pull-out forces.

Abstract: A method for producing of an electrooptical female connector element for an optical male connector of an electrooptical plug connector. In order to allow such a method to be carried out cost-effectively, a mounting module is used during the production of the female connector element. The mounting module is provided with alignment pins disposed on an end face, facing the male connector, in such a way that it corresponds to a configuration of alignment openings in the male connector. A component support having an electrooptical component with optical transducer elements is fitted on the end face of the mounting module, in a configuration corresponding to the optical conductor ends of the male connector. Once the male connector has been joined to the mounting module and the transducer elements have been actuated electrically, the component support is aligned to a position of maximum optical coupling.

On the distal end of the cable (8), there is a tiltable anchoring part (4, 5) with a cross section in the form of a parallelogram.

Abstract: A substrate is precisely positioned by a positioning element belonging to the substrate in an assembly device. While positioned in the assembly device, a converter is disposed and fixed on the substrate in a precise position relative to the positioning element. After that, the substrate is positioned precisely in an injection mold by the positioning element and surrounded by a moldable material, causing the formation of a molded body. The molded body has at least one functional surface, such as a lens or a stop face, serving the purpose of optical coupling.

Abstract: The invention relates to a self-centering arrangement of microstructured elements, particularly of microoptical components on a substrate serving as carrier. To provide microoptical components with projections that fit into corresponding recesses is known in the art. The invention provides a way to improve the mutual alignment of components (K1, K2) in that a deformation occurs when projections (Z1, Z2) are inserted into the recesses (A). This deformation may concern the projections or the recesses themselves or a molding material introduced between the projections and the recesses. The deformation improves the self-centering properties; in addition, manufacturing tolerances are more easily compensated. If the element cannot be provided with a suitable projection, an intermediate carrier is used, which is, for example, a plastic element produced by a LIGA process.

The plug connector part has a joining side facing toward the top side which is provided with second positioning structures that cooperate with the first positioning structures.
