An interferometric measuring device for measuring a surface or profile of an object includes a beam generating unit operable to generate a measurement beam with a spectral component at a wavelength smaller than 550 nm, a splitter to branch off an object beam and a reference beam from the measurement beam, a measurement probe connected to the beam generating unit and configured to direct the object beam onto the surface and to capture a portion of the object beam reflected from the surface as a signal beam, a signal analyzer connected to a detector unit and operable to derive a distance between the measurement probe and the surface on the basis of signals obtained from first and second detectors operable to detect first and second partial beams from an analysis beam being a recombination of the signal beam and the reference beam.
