Beam splitter for optical measurement systems for determining the characteristics of machine tools

摘要

The optical element in the form of a beam splitter which is used preferably in interplay with optical measurement systems for determining the characteristics on machine tools, or for other measurement purposes. A combination of five-edged prisms which are cemented or glued to one another is provided. The cement surface borders the partial mirroring (50%). The beam splitter is combined with at least one optoelectronic detector. With the latter the point of incidence of the light beam can be determined. A measurement system is formed of a plurality of units, each of which has a machine-mountable housing that encloses such an optical element.
