Abstract
Coordinate measuring machine, comprising an optical sensor for capturing image data of a workpiece. The optical sensor comprises a lens, which defines an optical axis, and an illumination device for illuminating the workpiece. The illumination device comprises a diffusely radiating luminous body and an optical filter having a plurality of separate light passages. Light emitted by the luminous body enters the filter on an underside thereof, passes through the light passages and emerges again from the filter on an opposite top side thereof. Each of the light passages transmits only light rays that form an angle smaller than a predefined limiting angle with a longitudinal axis of the respective light passage. The lens and the filter are inclined relative to one another in such a way that a normal vector aligned perpendicularly to the top side of the filter forms an inclination angle other than° with the optical axis.
