ABSTRACT:
An imaging device (10) for a printing form (12), has at least one first and one second laser diode bar (14, 16), the laser diodes (18) on the laser diode bars (14, 16) being disposed in lines. The device includes a first and a second micro-optics (21, 22) for generating aberration-corrected intermediate image spots of the laser diodes (18) and a macro-optical imaging optics (23) for generating image spots (24) on the printing form (12). The first and the second micro-optics (21, 22) are positioned in such a way in the emission regions of the first and second laser diode bar (14, 16) that the image spots (24) of the laser diodes (18) of the first and second laser diode bar (14, 16) lie at disjoint positions on the printing form (12), substantially along a spanning polyline (30). Also, a method is provided for arranging optical components in an imaging device (10) for a printing form (12).
