Beam transformation element, device for transforming electromagnetic radiation, method for producing a beam transformation element, and method for transforming an electromagnetic emission

A device for imaging a printing form in a printing form exposer, has at least one laser diode bar which has a number of laser diodes, which are each disposed along a line with nonuniform positional deviation. A spacing of the positions projected onto the line of two adjacent laser diodes differ from an intended spacing. An optical correction element is provided for changing a course of a light beam emitted by one of the adjacent laser diodes such that, downstream of the optical correction element, the beam courses of the emitted light from the two adjacent laser diodes follow the courses of two light beams from adjacent virtual laser diodes whose positions projected onto the line have a different or other spacing along the line, which have a smaller deviation in relation to the intended spacing than the spacing or is equal to the intended spacing.
