Abstract
In order to improve target illumination, a light source () of an emitter, which has a laser diode () configured as an edge emitter with a wavelength of 1,550 nm, has beam forming optics () mounted downstream in relation thereto, which comprise a cylindrical lens () and a first deflection element () with three fields having different diffraction structures. Said deflection element are located next to one another and crosswise in relation to the first fields and which also have different diffraction structures. Said deflection element directs the partial beams to the aperture of a collimator () in such a way that the partial beams substantially fill said aperture. The first deflection element () and a mount () for the cylindrical lens () are integral and, alike the second deflection element (), are made of plastic. Both parts are glued to opposite sides of the frontal areas of a block () made of glass.
