Optical microprobe for interferometric measurements in which a short-coherent light bundle has white light or at least two different spectral ranges, comprising: - a light-conducting fiber which transmits the light bundle and has a light output surface opening into the microprobe, - focusing optics for focusing the light bundle on the object surface, - a light path adjoining the light output surface of the light-conducting fiber for generating divergent light for exploiting the aperture of the focusing optics, wherein a measurement light bundle is reflected from the light output surface of the focusing optics to the object surface and from the object surface back through the microprobe into the light-conducting fiber and a reference light bundle generated by partial reflection at a reference beam splitter is reflected back into the light-conducting fiber, characterized in that - the reference beam splitter having filters (21, 22) which are partially reflecting in at least two different spectral ranges for generating at least two transmitted measurement light bundles (M 1, M 2) and associated reflected reference light bundles (R 1, R 2) of non-overlapping spectral ranges is arranged between the light output surface of the light-conducting fiber and the focusing optics, wherein an axial distance between two partially reflecting filters (21, 22) is adjusted in such a way that a spectrally induced optical path difference to which the respective measurement light bundles (M 1, M 2) are subjected when passing through dispersive elements in the light path to the object surface and back is present in the same magnitude between the respective reference light bundles (R 1, R 2), so that the dispersion-induced path difference is compensated when the measurement light bundles (M 1, M 2) and the associated reference light bundles (R 1, R 2) are superposed, and - the focusing optics has such a slight chromatic aberration that foci of the spectrally different measurement light bundles at least partially overlap at least in a desired measurement range for the object surface. - a light-conducting fiber which transmits the light bundle and has a light output surface opening into the microprobe, - focusing optics for focusing the light bundle on the object surface, - a light path adjoining the light output surface of the light-conducting fiber for generating divergent light for exploiting the aperture of the focusing optics, - the reference beam splitter having filters (21, 22) which are partially reflecting in at least two different spectral ranges for generating at least two transmitted measurement light bundles (M 1, M 2) and associated reflected reference light bundles (R 1, R 2) of non-overlapping spectral ranges is arranged between the light output surface of the light-conducting fiber and the focusing optics, wherein an axial distance between two partially reflecting filters (21, 22) is adjusted in such a way that a spectrally induced optical path difference to which the respective measurement light bundles (M 1, M 2) are subjected when passing through dispersive elements in the light path to the object surface and back is present in the same magnitude between the respective reference light bundles (R 1, R 2), so that the dispersion-induced path difference is compensated when the measurement light bundles (M 1, M 2) and the associated reference light bundles (R 1, R 2) are superposed, and - the focusing optics has such a slight chromatic aberration that foci of the spectrally different measurement light bundles at least partially overlap at least in a desired measurement range for the object surface.
