The invention relates to an arrangement for projecting the light emitted by a laser diode bar onto a focal plane (6). Said arrangement comprises a laser diode bar with several emission sources (1), which are situated adjacent to one another in a direction (X) and whose light strikes each time upon a slow axis collimation element (4, 4') and is superimposed with the light of the other slow axis collimation elements (4, 4') after passing through a slow axis focussing lens (5) in a focal plane (6). At least two groups of slow-axis collimation elements (4, 4') are provided that differ in that at least two images, which are slightly offset with regard to one another are produced in the focal plane (6) in the direction (X), in which the emission sources (1) are adjacently arranged, so that the intensity distribution (9) of the image produced in the focal plane (6) is comparatively homogeneous. |
