Abstract
A device for recording images on a printing form (), having at least one laser diode bar (), which includes a number of laser diodes () whose image spots () lie disjunctly in an image field (), and having an array () of microlenses () positioned in the emission region () of the light radiated by the laser diode bar, one microlens () being assigned to each optical path () of a laser diode (). The device is distinguished in that at least one first laser diode () and one second laser diode () are densely positioned on the laser diode bar () in such a way that the first optical path () of the first laser diode () and the second optical path () of the second laser diode () run through a first microlens () of the array. The device can be used, in particular, in a print unit or a printing press and, at a given width of the laser diode bar, makes it possible to provide a greatest possible number of imaging channels ().
