The Moore M48 CMM has been a vital instrument for achieving precise measurements of physical dimensions and standards. This primary CMM, which has been in operation at NIST since 2000, boasts remarkable capabilities, using a touch probe and integrated laser interferometers to measure distances between points on an object in three dimensions with a sensitivity of ten billionths of a meter. It has been heavily relied upon by various customers, including the military, academia, government calibration and research labs, private industry calibration labs, and manufacturers.
