We offer optical 3D surface measurement systems for quality assurance in research and production. Our core competence is the measurement of surface roughness and form also across large measurement areas and volumes. The cutting edge measurement and the measurement of smallest radii and angles are typical applications. Focus-Variation, the technology of the InfiniteFocus line, combines the traditional surface metrology and the micro coordinate measurement technology. This technology achieves traceable and repeatable results in highest resolution even in production.
