    摘要： A GRIN fiber lens connection system particularly suited for high-power laser applications is disclosed. In one aspect, a GRIN fiber lens expanded beam system that is efficient over a wide spectral region, e.g., a range of about 200 nm, 300 nm or 400 nm, is disclosed for coupling one optical fiber (such as a single-mode fiber) to another. For example, a GRIN fiber lens expanded beam system is efficient over a range of wavelengths from about 400 nm to about 800 nm, from about 190 nm to about 390 nm, or from about 1270 nm to about 1650 nm. A method for designing such a coupling system is also disclosed. In another example, the cores of the GRIN fiber lenses are substantially devoid of germanium, and the cladding is doped with an element, such as fluorine, that lowers the refractive index of the cladding.

    摘要： The invention relates to contactless plug connectors and contactless plug connector systems for electromagnetically connecting a corresponding mating plug connector. In order to allow for an electromagnetic connection, the invention suggest providing at least one input terminal for inputting a baseband input signal; an antenna element arranged at the mating end of the contactless plug connector; and a transmitting circuit for modulating the inputted baseband input signal on a predetermined carrier frequency and for transmitting the modulated baseband input signal via the antenna element as a radio wave with the predetermined carrier frequency. In particular, the contactless plug connector and contactless plug connector system include an electromagnetic shielding element arranged to surround the transmitting circuit and the antenna element with a rim portion forming an opening at the mating end of the contactless plug connector.

    摘要： The present invention relates to a contact element (3, 3′, 3″), a base (2, 2′, 2″, 2′″), a clamping element (4, 4′, 4″), an arrangement (1, 1′, 1″, 1′″, 1″″, 1′″″) and a mounting section (301, 301′, 301″) for electrically contacting a light-emitting diode (LED) (100, 100′). In order to conveniently and cost-effectively hold and electrically contact the LED (100, 100′), the present invention provides that the contact element (3, 3′) comprises a mounting section (301, 301′) adapted for mounting the contact element (3, 3′) to the base (2, 2′) in a manner that the contact element (3, 3′) is pivotable about a pivot axis (P) extending through the mounting section (301, 301′), and comprises a contact arm (302, 302′) protruding laterally from the mounting section (301, 301′) and having on a distal end a contact point (303) facing essentially in a contact direction (K) for contacting the LED (100), wherein the contact direction is running essentially in parallel to the pivot axis (P). Further, the invention provides that the base (2, 2′, 2″) comprises at least one contact receptacle (203, 203′, 203″) which is adapted to accommodate a contact element (3, 3′) according to at least one of claims 1 to 10 in at least to different rotational positions (R1, R2), and that the clamping element (4, 4′, 4″) comprises an attachment section (401, 401′) adapted to be attached to the base (2, 2′) at the at least one contact receptacle (203, 203′, 203″), and a holding section (402, 402′) adapted to hold down the contact arm (302, 302′) of the contact element (3, 3′) towards the LED (100, 100′).
