  • Optical plate for calibration of coordinate measuring machines
    Patent number: 9372079
    Abstract: A coordinate measuring machine is calibrated by taking optical measurements of an optical flat that includes a grating placed on its surface. The arm of the CMM capable of multi-directional translation in relation to an object is fitted with a white-light interferometric objective and optical measurements are taken of the flat while translating the objective (or the flat) in the coordinate direction subject to calibration. The objective may serve also as the probe of the CMM.
