Abstract

Assembly for optical beam transformation, which is useful for imaging a light source (1) or several light sources onto the front face of an optical fiber (7), comprising at least one light source (1) that is capable of emitting at least one beam of light (9) and further comprising one imaging element (2) and at least one device (3) for optical beam transformation, the imaging element (2) being able to image the at least one beam of light (9) emitted from the at least one light source onto the at least one device (3) for optical beam transformation through which the at least one beam of light can at least partially pass and the at least one device (3) for optical beam transformation being able to rotate the at least one beam of light (9) passing through said device at least in sections about the direction of propagation (z) of the respective section of the beam(s) of light by an angle of about 90°, the device (3) for optical beam transformation comprising at least one segment of cylindrical lens (8) on one entry and/or exit plane of the beam(s) of light (9).
