The ZeGage™ Pro and ZeGage™ Pro HR profilers are Coherence Scanning Interferometers (CSI) that provide 3D optical surface profiling for the measurement of precision surfaces. Unlike other optical surface profilers, these systems maintain high precision at all of their magnification options. They are not affected by the environment they operate in. You can take them out of the QA lab, place them directly beside your production equipment, and get precise 3D surface metrology.
