Abstract:
1. A device for imaging a printing form, the device comprising: at least one laser diode bar having a number of laser diodes disposed in a row with nonuniform positional deviation along a straight line in a direction of said row of said laser diodes, an actual spacing of positions projected along a perpendicular onto said line of two adjacent said laser diodes differing from an intended spacing; and at least one optical correction element for changing at least one course of a light beam emitted by one of said adjacent laser diodes, said optical correction element changing the at least one course such that, downstream of said optical correction element, beam courses of emitted light beams from said two adjacent laser diodes are the courses of two light beams from adjacent virtual laser diodes whose positions projected along the perpendicular onto said line have a different or other spacing along said line, which have a smaller deviation in relation to the intended spacing than the actual spacing or is equal to the intended spacing.
