Light-emitting table suitable for use in metrology, and coordinate measuring machine having such a light-emitting table

摘要

A light-emitting table suitable for use in metrology includes a plurality of light sources and a field to be illuminated. Light-emitting centers of the light sources represent starting points of light source axes which perpendicularly intersect the field to be illuminated. The light-emitting centers of the light sources on one side and the field to be illuminated on the other side delimit an intermediate space in the interior of the light-emitting table. Located between the light source axes within the intermediate space are curved and mirrored surfaces, the focal points or caustics (K) of which are located within the intermediate space between the curved and mirrored surfaces and the field to be illuminated. A coordinate measuring machine for capturing the coordinates of a workpiece includes at least one optical sensor and a light-emitting table for illuminating the workpiece during measurement of the coordinates of the workpiece using the sensor.
