Abstract: The invention relates to an optical light guiding system, comprising an interface for coupling in and/or an interface for decoupling data and at least one data channel for transmitting data, and a method for transmitting data in optical systems, comprising the steps of coupling data into an interface of a beam guidance element; the transmission of the data by means of a first and/or a second data channel, which are arranged within the beam guiding element (or the casing), wherein the data channels can also be used for the fractional monitoring of the beam guiding element; and decoupling the data from an interface.

Abstract: A device for the protection of laser optics or to their lifetime increase. The device for the protection of laser optics comprises a housing arranged below a laser optics housing with a connection for the supply of a cutting gas, and on the opposite side to the laser optics outlet nozzle for the cutting gas and a pressure-resistant protective glass on the side of the laser optics and a process-side protective glass, which is arranged between the nozzle and pressure-resistant protective glass available.

Abstract: A light guide or beam guiding system with safety component and a method for its breakage monitoring. The present invention provides a fiber optic cable comprising a power fiber as well as first and second channels for break and plug monitoring of the power fiber, wherein the first and second channels may be separate.

Abstract: A socket for a releasable and reproducible assembly with an optical fiber plug. The socket has a main housing and an access shaft for inserting an optical fiber plug with a plug housing. At the inner end of the access shaft an optical fitting surface is arranged that is inverse to an optical fitting surface of the optical fiber plug. The main housing has a knurled ring, at least one movable engagement pin and a locking ring. The closing path of the engagement pin is formed by a guiding groove in the locking ring with at least two sections. The guiding groove has a first azimuthally extending portion and a second axially extending section with a recess at the end region of a transversal groove. A friction-locked snapping in of the engagement pin into the recess at the end region of the transversal groove occurs.

Abstract: The invention concerns an optical device and its application to generate an adjustable wave front deformation of a laser beam and thus to generate an adjustable beam spot geometry in the focal plane of laser optics. For this purpose, a device is provided which allows adjusting and modifying a laser beam in such a way that a beam spot, the shape of which can be adjusted continuously based on the original focal shape, is generated after focusing the beam, i.e. at least one dimension parameter of the shape of the beam spot has to be variable and adjustable so that the beam parameter product of the beam can also be modified without having to modify the focal position.
