ABSTRACT:
The invention relates to an optical beam divider which subdivides a beam (A), more particularly a laser beam, into at least two beams (B, C) which differ from the original beam (A) only in intensity. To this end the beam divider has a deflecting mirror (2) which is disposed in the path of the beam (A) and which rotates around an axis lying perpendicular to the plane of the mirror and has at least one window (2c) which sweeps the whole cross-section of the beam (A) when the deflecting mirror (2) rotates.
