Optical 3D measuring device for shape & finish

InfiniteFocusSL is a cost-efficient optical 3D measuring device for simple, fast and traceable measurement of shape and surface finish on micro structured surfaces. Users measure both shape and finish of components with only one system.

Highlights of InfiniteFocusSL

Form & Roughness with one system

Focus-Variation

The technology combines the small depth of focus of an optical system with vertical scanning to provide topographical and color information from the variation of focus.

Full form measurement

Real3D

Users measure surfaces from numerous perspectives. Single measurements are automatically merged into a full 3D dataset. High-precision and calibrated rotation and tilt axes ensure automated, repeatable and traceable measurement on the whole measurement object.

Precise, fast & flexible

5 axes metrology

The expansion from 3 to 5 axes allows measurements of geometries that are otherwise difficult or impossible to access. High-precision tilting and rotating axes enable the measurement of GD&T and roughness parameters on the entire measured object.

What else is possbile with InfiniteFocusSL

Success story: Optical metrology & AI ensure reliable powertrain technologies

For the implementation of a new laser cleaning process, automotive supplier Vitesco Technologies was looking for a measuring device to monitor the performance and quality of laser processing in series production. The Bruker Alicona 3D measurement system offers a new classification software in addition to 3D topography measurement. Based on AI, the software automatically detects OK and not OK surfaces.

Measurement report: Plug connections

Plug connections of the most diverse types are used in electromechanical components in billions of cases. A high precision and a perfect fit is mandatory for the long lasting use of the components. With InfiniteFocusSL all required parameters of the pins are measured easily and fast. The results are repeatable and user indipendent. Also various pin variants with different surfaces can be measured.

Success story: Measuring the geometry of pins optically in 3D

Frank Uibel, a long-time expert in the field of press-fit technology and active member of the IPC, recommends Bruker Alicona technology as a "fast, simple and accurate measuring tool" for the geometric verification of press-fit zones. We wanted to know why and asked him a few questions.
