ABSTRACT:
Method for carrying out the non-contact measurement of geometries such as surfaces of objects, with a coordinate measuring machine with a laser beam that is projected onto a measuring point of the object via an optical system, and in which the light that is reflected or scattered by the measuring point is detected by a detector. The optical system includes a zoom lens, whose lens groups each are each motor-adjusted separately from each other in positions for working distance and/or resolution and/or measuring range.
