Title: DEVICE AND METHOD FOR PRODUCING A LIGHT BEAM
Abstract:
The invention relates to a device (1) for producing a light beam, comprising at least a first and a second light source (2, 3), wherein the first and the second light sources (2, 3) preferably emit light of the same wavelength during operation. The light sources (2, 3) are arranged in relation to each other in such a way that the beam profile (11) of the first light source (2) is rotated in relation to the beam profile (12) of the second light source (3) by an angle of rotation D about an axis A in the direction of the light propagation. A beam rotation element (4) is arranged downstream of at least one of the light sources (2, 3), which beam rotation element causes a rotation of the beam profile by an angle in such a way that the beam profile (11, 12) of the light source (2, 3), after passing through the beam rotation element (4), is oriented substantially the same in a plane perpendicular to the propagation direction A of the light as the beam profile (11, 12) of the other light source (2, 3) in the plane perpendicular to the propagation direction.
