Among variety of methods to measure complex surfaces, coordinate measurement is widely used in reverse engineering and measuring complex topography. In this paper, a coordinate measuring system based on 3D tactile probe is introduced. This system can measure complex surface with resolution of 1nm, measuring range of 25mm×25mm×5mm. The component of the measuring system, the principle and advantages of the probe are also introduced as the major part. We used the nano-CMM to test an optical reflector with sine curve surface. The fluctuation of the topography is about 5 micrometers. The result is compared with the data of AFM and the source of deviation is analyzed in the conclusions.
