More than 15 years of Focus-Variation


Based on the technology of Focus-Variation, our measuring systems close the gap between classical dimensional metrology and surface roughness measurement. Users can measure both GD&T features and roughness parameters robustly, accurately, traceably and with high repeatability even under production conditions by using only one optical sensor. With Vertical Focus Probing it is now possible for the first time to optically probe components laterally and thus to measure even vertical flanks of more than 90°.

Focus Variation

Form and roughness in one system

Our measuring systems, which are based on focus variation, combine the functionalities of a surface measuring instrument with those of a form measuring system. Focus-Variation combines the small depth of focus of an optical system with vertical scanning to provide topographical and color information from the variation of focus. The main component of the system is a precision optics containing various lens systems that can be equipped with different objectives, allowing measurements with different resolution.

Vertical Focus Probing

Optical measuring technique enables lateral probing of components

Up to now, geometries such as bore holes of injection valves in the automotive industry were difficult to measure optically. The lateral probing of components with vertical surfaces was limited to tactile measuring systems, CT solutions or complex customized solutions. This changes with Vertical Focus Probing, an extension of Focus-Variation technology. Based on areal measurements, the optical probing of components over the entire surface is possible.

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.
