Measuring form deviation and roughness together

The surface quality of raw products is crucial to guaranteeing that products will work perfectly later on. Metallic implants in dentistry, for instance, require a particularly low level of roughness. In contrast, many raw products depend on a particular level of roughness for subsequent painting and coating processes. Some applications even call for concurrent information about form deviation and roughness. The TopMap models from Polytec allow you to firstly determine form deviations with nanometer resolution and a large measurement volume even on large areas, and then to measure the roughness in a small area. While you conduct areal analyses with the models in the TopMap series, an integrated chromatic confocal sensor also determines roughness profiles. You can characterize the entire surface, calculate volume and exactly determine peaks and valleys on behalf of the examined distance parameters.
