Non-contact Measurement: Optical Dimensional Metrology

Discover non-contact dimensional metrology for the precise measurement of surface roughness and geometry. The optical 3D measuring machines from Bruker Alicona enable the lateral probing of your components and thus the non-contact measurement of vertical flanks with more than 90°. This not only offers you a comprehensive analysis of the component geometry, but also fast, automated and traceable measurements of your components, perfectly adapted to the requirements of precision manufacturing.

Optical dimensional metrology closes the gap between classical dimensional metrologyy and surface roughness measurement. This combination is used in all areas of precision manufacturing, from aerospace and medical technology to the automotive industry. Precise measurement results not only ensure compliance with strict quality standards, but also optimize your production processes in the long term. Discover the possibilities of optical dimensional metrology and set new standards in the quality assurance of your components!

Profile based and area based surface roughness parameters
Easy-to-use software, fast processing and accurate measurements
Full form measurement

Why non-contact Measurement?

The advantages of non-contact measurement are obvious: While probes that travel over the surface can leave damage, the components measured without contact remain completely undamaged. Tactile roughness measurement systems experience limitations with particularly narrow valleys due to the diameter of the probe. Non-contact measuring devices, on the other hand, can accurately represent even the finest depths on the surface. Also, areal measurements with reasonable time and money resources are only possible with non-contact. The following Bruker Alicona technologies make non-contact form and roughness measurements possible:

FOCUS-VARIATION

Non-contact measurement of shape and roughness in one system

Our optical 3D measuring systems, which are based on Focus-Variation, combine the functionalities of a surface roughness measuring instrument with those of a form measuring system. Focus-Variation merges the small depth of focus of an optical system with vertical scanning to provide topographical and color information from the variation of focus. In other words: It delivers information about shape and roughness of a surface in one go without contact, which makes it super-efficient.

Faster non-contact measurement of points & contours

Vertical FOCUS PROBING

Optical lateral probing of components

Up to now, geometries such as bore holes of injection valves in the automotive industry were difficult to measure optically. This changes with Vertical Focus Probing: The technology enables optical, lateral probing of vertical flanks of more than 90°, over the entire surface. Users measure holes, reference surfaces, lengths, contours, etc. with high precision contact-free, in high resolution and fast measuring times.

Focus-Probing

Faster non-contact measurement of points & contours

For the first time, Focus-Probing technology enables users to measure single 3D points and 3D contours very quickly without the need for vertical scanning. It enables the measurement of metrically correct contours at a single position. 3D contours and points obtained with Focus-Probing can be used, for example, to quickly measure features such as distances and diameters, or to align a sample with a CAD dataset.

REAL3D

Full form measurement

Using Real3D, users measure surfaces from numerous perspectives. Single measurements are then automatically merged into a full 3D dataset. High-precision and calibrated rotation and tilt
axes ensure automated, repeatable and traceable measurement of form and roughness on the whole measurement object. Users are able to visualize and measure surface features such as diverse flank angles, thread pitch and undercuts.
