Roughness measurements

... according to standard

Using the technology of the structured illumination confovis measuring systems are particularly suitable for precise measurements of surface roughness, which were analysed profil-based (2D) according to DIN ISO 4287/4288 as well as area-based (3D) according to DIN ISO 25178.

3D surface metrology provided by confovis

Quick, precise and conforming to standards: confovis offers optical 3D measuring technology for reliable process controls and detailed quality inspections in a wide range of industries.

With cutting tools, the surface quality in the sub-micrometer range is crucial to the service life of the tools and the precision of the parts to be produced. Especially in the production of functional surfaces such as bearing surfaces, deviations in the nanometre range are decisive for the service life and reliability of the parts. Using confovis measuring systems, you can measure both tools and functional surfaces of components with nanometre precision.

Artefact-free measuring

The patented functional principle of structured illumination of confovis offers new approaches in confocal measurement technology. The latest generation of devices guarantees an isotropic resolution of edge angles up to 40°. Even at structures with an edge angle of up to 90°, there are no artefacts, whereby a minimum lateral resolution of 300 nm is achieved. In this connection, the photon noise of better than 3 nm constitutes the limit of the axial resolution. The confovis measuring process uses LEDs und thus reduces Speckle and coherence effects that often limit the accuracy of measuring results with white light interferometers and laser scanning microscopes.

The confovis measuring process uses LEDs, thus reducing the effects mentioned. Measuring artefacts, the main cause for the restriction of the confocal measuring technology applied to determine roughness values of unknown surfaces, are reduced considerably. Together with the actually recorded measured values, this allows traceable roughness measurements.
