Non-contact Measurement: Optical Metrology & Dimensional Metrology

Optical metrology enables precise and non-contact measurement of components. With the help of light, information about the shape and roughness of surfaces and geometries can be captured and analyzed. Its broad range of applications and robust design make it an excellent choice for industrial quality assurance. With optical metrology from Bruker Alicona, you are able to perform complex measurement tasks in production. The measuring instruments combine the advantages of Focus-Variation technology with user-friendly software and a robust design, making them an excellent choice for industrial applications.

The optical 3D measuring machines from Bruker Alicona also 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.

Why optical metrology?

The advantages of optical metrology are clear: While probes that travel over the surface can leave damage, the components measured without contact remain completely undamaged. 
Traditional roughness measurement systems struggle with narrow valleys due to the diameter of the probe, whereas optical measuring devices precisely capture even the finest depths on the surface. 

Why optical metrology

Optical dimensional metrology

Bruker Alicona optical dimensional metrology enables the measurement of dimension, position, shape and roughness of components with one optical sensor. It 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. Dimensional metrology offers faster, more accurate measurements and can be easily automated. By integrating it into your manufacturing processes, you can improve efficiency and significantly reduce scrap rates.

Optical metrology for non-contact form & roughness mesurement

Form & roughness in one system with Focus-Variation

FOCUS-VARIATION

Non-contact measurement of shape and roughness in one system

Our optical 3D measuring systems, which are based on Focus-Variation technology, 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.

Vertical FOCUS PROBING
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.

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.

Full form measurement with Real3D

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.
