with one or more cylindrical lenses, which collimate each light beam in the y-direction, where by rotating at least one of the cylindrical lenses around the z-axis or by providing a discontinuous diffracting element, each light beam is diffracted at a different diffraction angle in the y-direction. The device additionally contains a director-collimator optical unit

3

, which collimates each light beam in the x-direction and diffracts at different diffraction angles so that the main beams of the individual light beams in the x-direction converge at a specified distance from the emitter and run parallel in the y-direction. Finally, the device has a redirecting optical unit

which compensates for the diffraction of the light beam in the x-direction caused by the director-collimator optical unit
