Abstract

The microoptical device has beam-parallelizing optics and a deflecting mirror configuration. The device converts a laser beam bundle, which is emitted by a laser diode strip structure or individual diode chips and which is comprised of a plurality of strip-shaped individual laser beams, into a rectangular or parallelogram-shaped laser beam bundle composed of parallelized strip-shaped individual laser beams arranged parallel next to one another. The beam-parallelizing optics may be a cylindrical lens, and the deflecting mirror configuration may be two rows of mirrors. The cylindrical lens and the rows of mirrors are preferably produced from a semiconductor material and they can therefore be produced cost effectively by means of methods used in semiconductor process engineering.
