Patent ID: 7317470

Claim:
An imaging device for a printing form comprising: a first laser diode bar having first laser diodes disposed in a first line and having a first emission region; a second laser diode bar having second laser diodes being disposed in a second line and having a second emission region; a micro-optical array for generating aberration-corrected intermediate image spots of the laser diodes, the micro-optical array including a first micro-optics and a second micro-optics; a single macro-optical imaging optics for generating image spots of the intermediate image spots of the first laser diodes of the first laser diode bar and of the second laser diodes of the second laser diode bar on the printing form, the first micro-optics being positioned in the first emission region and the second micro-optics being positioned in the second emission region so that image spots of the first laser diodes of the first laser diode bar and of the second laser diodes of the second laser diode bar lie at disjoint positions on the printing form along a spanning polyline, the spanning polyline being representable as a function of a variable of a spanning direction of the printing form; each of the first and second laser diodes of the first laser diode bar and the second laser diode bar being individually controllable.
