ABSTRACT A recording arrangement for processing images for manufacturing printing forms wherein modulated laser light containing the image passes through a multi-mode waveguide to a recording element and wherein the modulated laser light beam illuminates a diaphragm which is imaged on a light sensitive recording medium for the exposure. A multi-mode light waveguide has a disadvantage in that the light distribution at its exit surface is unequal because of the modes formed in the light waveguide. Thus, the diaphragm will be unequally illuminated and the exposure plane will have non-homogeneous light distribution so that the exposure of the recording medium is uneven. In the present invention, a scattering disc (6) and an additional convergent lens (13) is placed between the exit surface (2) of the light waveguide (1) and the diaphragm (17) and the spacing are selected so as to obtain the desired result which gives homogeneous illumination of the diaphragm and accurate and even recording.
