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.

Method for carrying out the non-contact measurement of a surface of an object, comprising:
- projecting a laser beam from a coordinate measuring machine onto a measuring point of the object via an optical system,
- adjusting a plurality of lens groups of a zoom lens assembly, wherein each of said plurality of lens groups is adjusted in zoom independently and separately by a motor for modifying a working distance, resolution and measuring range, and
- detecting the light reflected or scattered by the measuring point via detectors.
