ABSTRACT:
The deflection of a light beam in two mutually perpendicular directions ensues by rotating two spindles which are hinged to a single deflection mirror and whose axes reside perpendicular to one another. The first spindle is hinged to the deflection mirror via a fork joint such that the trunnion axis of said fork joint and the axis of the first spindle are perpendicular to one another. The second spindle is hinged to the deflection mirror via a turning arm and a dog secured to the backside of the deflection mirror. So that the two spindles can be turned independently of one another, the dog is guided in the turning arm so as to be freely pivotable around the axis of the first spindle. The dog is preferably guided in a slot of the turning arm. Apparatus equipped with only a single deflection mirror for the deflection of a light beam in two mutually perpendicular directions are usefully employed in laser labeling.
