InfiniteFocus for form and roughness measurement

Surface metrology and form measurement in only one system

InfiniteFocus-Standard at a glance


  • The system: measuring form and roughness
  • The benefits: measuring of steep flanks and small radii
  • The applications: from tool imeasurement to 3D measurement of micro machined components and turbine blades
  • The technology: Focus-Variation for areal based 3D measurement
  • The additional bonus: no wear, no maintenance and provable accuracy

The system: measuring form and roughness

InfiniteFocus is an optical 3D micro coordinate system for form and roughness measurement. Measurements achieve a vertical resolution of up to 10nm. This system also operates on large measurement areas and volumes. Its results are traceable and ensure repeatable accuracy. Users benefit from these features, those of a coordinate measurement system and those of a surface measurement instrument.

The benefits: measurement of steep flanks and small radii

Even steep flanks of 85° are measured with highest vertical resolution. InfiniteFocus also obtains high-resolution measurement results when it comes to surfaces of various textures. This also applies to components with small radii and angles. In addition every measurement is provided with color information registered to the 3D data. The optional 360° measurement enables a full form measurement.

The applications: from tool measurement to 3D measurement of micro machined components and turbine blades

InfiniteFocus is used for cutting edge measurement of drills, milling cutters and other tap tools. Other applications are micro precision, medical technology, material science and the paper and print industry. It is also often used for quality assurance applications such as micro diecasting, forensics and micro electronics.

The technology: Focus-Variation for areal based 3D measurement

InfiniteFocus is based on Focus-Variation. The optical technology delivers a measurement density of more than 100 mil measurement points which enables form and roughness measurement of even large measurement areas and volumes. As an area based technology, Focus-Variation is already included in the most recent EN ISO standard 25178. With each measurement, users automatically receive data for evaluating the measurement uncertainty.

The additional bonus: No wear, no maintenance costs and provable accuracy

InfiniteFocus is a 3D measurement system without wear, nor maintenance costs. Automation options make the 3D micro coordinate measurement machine a user friendly measurement device with provable accuracy. A number of measurement standards prove the accuracy of the optical roughness and form measurements.

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.
