OPTICAL ROUGHNESS MEASUREMENT
The optical 3D sensor WM | RS-C is an surface measuring white light interferometer and was developed for measuring, characterizing and inspecting topographies, roughness and finest structures in a microscopic environment. The WM | RS-C captures 3D surfaces as a point cloud or triangulated STL mesh and thus enables DIN EN ISO-compliant 2D and 3D roughness evaluation. The particular strength of the sensor lies in the measurement of vertically and horizontally high-resolution surfaces. The optical 3D sensor WM | RS-C uses the short coherence length of „white“ light to measure technical surfaces vertically at highest resolution. An internal GigE camera with full HD resolution and an integrated LED with optimized spectral distribution are used. The interferometer is usually operated with exchangeable Mirau lenses. In the table version, the interferometer works with a piezo-driven actuator, which enables high-resolution scanning of topographies.
