Abstract:
1. A measuring device for measuring a focussed laser beam, comprising: a magnification lens system including at least two lenses disposed one after another along a beam path of the laser beam, wherein each pair of successive lenses of the magnification lens system has coinciding focal points; an electronic image sensor disposed behind the magnification lens system at a focal point thereof, for capturing a magnified image of the laser beam; an adapter, which encloses the beam path, for coupling the measuring device to a laser apparatus providing the laser beam, the adapter forming an abutment surface for the laser system; and longitudinal adjustment means permitting a simultaneous adjustment of the lenses of the magnification lens system and the image sensor along the beam path with respect to a reference point of the measuring device provided on the adapter such that the lenses of the magnification lens system and the image sensor are simultaneously moved with respect to the reference point.
