ABSTRACT:
A co-ordinate-measuring instrument is provided with a translumination device which includes at least one illumination body and an image processing sensor system which is provided with a lens measuring along an optical axis. In order to perform high-accuracy measurement without the necessity of placing and removing the illumination body and the sensor image processing system, the illumination body is constructed in such a way that it emits diffused light and a filter which is embodied, for example in the form of a comb, provided with through holes and arranged between the illumination body and a measured object is transparent for beams forming with the axis an angle which is less than a defined limiting angle α.
