Area based measurement conforming to EN ISO 25178

Focus-Variation is an area based technique for 3D surface measurement in highest vertical resolution. Form and roughness are measured with a measurement point density of up to 100 mil measurement points. Results are repeatable and traceable. The technology makes use of the limited depth of focus of an optic. Focus-Variation is included in the most recent EN ISO standard 25178.

Results include measurement uncertainty information

Measurement results are always composed of both measurement value and the measurement uncertainty. Focus-Variation adds information about the estimated repeatability to each 3D measure point. With every measurement value, users receive an estimated measurement uncertainty. That increases quality and validity of the measurement value.

Stable and quick measurements in research and production

Focus-Variation is a robust technology for 3D surface measurement. Even under harsh operating conditions, users achieve high resolution results. The stable technology is also insensitive to environmental influences such as temperature or ambient light, as it is operating with a large data volume. At the same time, Focus-Variation is extremely quick: measurement times depending on the surface texture lie within a range of only a few seconds.

Measurement modules for 3D surface measurement with Focus-Variation

All measurement modules of the InfiniteFocus product group are based on Focus-Variation. These include measurement of profile form and profile roughness, measurement of surface texture for area based roughness measurement, volume measurement, 2D measurement and automation. Additional measurement modules enable complete form measurement and the measurement of form deviations, automatic wear analysis as well as cutting edge measurement.

3d micro-coordinate measurement technique for roughness and form measurement

Alicona offers optical 3d surface measurement systems for quality assurance in research and production. Core competence is the measurement of roughness and form also across large measurement areas and volumes. The cutting edge measurement and the measurement of small radii and angles are typical applications. Focus-Variation, the core technique 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.
