Abstract

A device focuses laser light into a working plane. The device contains a deflection mirror and a cylindrical lens. A lens apex of the cylindrical lens has an offset and which has a first transmission portion and a second transmission portion different from the first transmission portion. The device further has retroreflector device with an optical axis. The deflection mirror is arranged in the beam path of the device such that it can deflect the laser light during the operation of the device such that the light can propagate substantially parallel to the optical axis of the retroreflector device and can be transmitted through the first transmission portion of the cylindrical lens, and can then be reflected back by the retroreflector device such that the laser light can be transmitted through the second transmission portion of the cylindrical lens and can be focused into the working plane.
