摘要

A device for rotating an emitter device emitting a laser beam L about a rotation axis for the purpose of generating a plane or a conical surface has an elongated body of revolution 2 which carries the emitter device 1 and is held rotatably at the ends on a fixed holder 5 by means of a pivot bearing 3, 4 in each case, the pivot bearing 3, 4 comprising a conical seat 16 and a bearing member 17 engaging in the latter and having a rounded outer surface concentric with the rotation axis, and the conical seat 16 and the bearing member 17 being prestressed (20) against one another.
