摘要： The invention relates to an assembly for correcting laser illumination emitted from a laser light source, comprising a laser light source, which has linear emission sources that are arranged in a row in a first direction (X), whereby in addition, the emission sources that are arranged essentially in a row are at least partially offset relative to the row in a perpendicular direction (Y) in relation to the first direction (X). The assembly also comprises corrective elements, which can correct the laser illumination emitted from the laser light source in such a way that the spatial distortion of the laser illumination, caused by the offset position of the emission sources relative to the row, is compensated. According to the invention, the corrective elements are configured as a plate array that comprises a number of plate elements consisting of substantially plane-parallel plates that are transparent to the laser illumination used. At least two of the plate elements have a different thickness and the corrective mans is located in the laser illumination emitted from the laser light source, in such a way that the light beams emitted from at least two emission sources that are offset in relation to one another are subjected to a respective beam offset of a different magnitude by two different plate elements, thus compensating the distortion caused by the offset position of the emission sources. The invention also relates to a method for producing the aforementioned assembly.

摘要： An apparatus for generating electron radiation comprises a wire-shaped hot cathode that is much more extensive in a longitudinal direction than in a transverse direction. Electron radiation emerges from the hot cathode that, due to the elongated shape of the hot cathode, exhibits an elongated, line-shaped cross section perpendicular to its direction of propagation, where the extension in longitudinal direction of the line is significantly greater than in transverse direction of the line. The apparatus further comprises a cathode electrode and an anode. A voltage for accelerating the electrons emitted from the hot cathode is applied between the cathode electrode and the anode. The hot cathode is arranged to be spaced apart from the cathode electrode such that electrons that are accelerated to the anode are emitted from the hot cathode in each of the transverse directions.

摘要： A device for homogenizing light contains at least one optically functional surface through which light to be homogenized can pass and a plurality of concave and convex cylindrical lenses which are disposed in an alternating fashion one next to the other on the at least one optically functional surface. The device further has at least one first embodiment and at least one second embodiment, different from the at least one first embodiment, of transitions between the concave and the convex cylindrical lenses. Wherein the transitions between the concave and the convex cylindrical lenses are configured such that partial beams of the light to be homogenized, which have passed through different embodiments of the transitions between the concave and the convex cylindrical lenses, have an optical path difference with respect to one another, which contributes to the reduction of interference effects in the homogenized light.
