Accuracy Specification Format of the Laser Tracker

The accuracy specifications of the tracker are written per the ASME B89.4.19 Standard - accuracy is expressed as Maximum Permissible Error (MPE). The MPE is a magnitude and not bandwidth. For example, if the MPE for a particular measurement is 75 microns, the maximum error of the measurement is +75 microns or -75 microns. It is not +37.5 microns or -37.5 microns. Typical performance of the tracker is half of the MPE values and it is these typical performance values that are provided in the marketing literature. The accuracy of the tracker can be found in the Tracker manual.
