More Information
Summary:Disclosed herein is a contactless sensing unit for a measuring apparatus or machine tool 1, notably for a coordinate measuring machine (CMM). The contactless sensing unit comprises an optical probe device, a coupling element for mechanical connection to a complementary coupling element on the measuring apparatus or machine tool and a housing for housing the optical probe device. The housing is mechanically connected to the coupling element. The optical probe device comprises an optical objective at a distal end of a lower portion of the probe device for sensing a surface of a workpiece. The contactless sensing unit further comprises a collar for adjusting a relative axial, radial and/or angular position of the optical probe device with respect to a fastening portion of the housing. The collar circumferentially clamps the optical probe device essentially around an upper portion of the optical probe device.
