Dimensional accuracy & surface finish measurement
InfiniteFocusG5 plus
InfiniteFocus is a highly accurate, fast and flexible optical 3D measurement system. With only one sensor, users verify dimensional accuracy and measure surface roughness of their components. Based on the technology of Focus Variation the range of measurable surfaces is almost unlimited. By means of Vertical Focus Probing, which is an extension of Focus-Variation vertical surfaces are probed laterally as well. Components are traceably measured in high accuracy, with a high vertical resolution and in high repeatability. The robust measurement principle of Focus-Variation in combination with a vibration-isolating hardware enables the form and roughness measurement of also large and heavy components. All axes of InfiniteFocus are equipped with highly accurate encoders ensuring precise stage movement. With an automation interface, InfiniteFocus is also applied for fully automatic measurements also in production.

High measuring point density
Up to 500 million measurement points ensure a meticulously detailed measurement with tolerances in the μm and sub-μm range along with large working distance. The high measurement point density of Focus-Variation enables operators to gain a consistently high lateral and vertical resolution across high measurement volumes.
NEW: Measurement of flanks with more than 90°
Vertical Focus Probing is an extension of the Focus-Variation technology and hence a pure optical measurement technology. It allows the measurement of surfaces with slopes of more than 90° and micro holes directly without articulating the sample during the measurement.
Full form measurement with Real3D
Using 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.

Pick & Place with InfiniteFocus
The measurement solution Pick & Place was presented at Advanced Engineering Show 2019 in the UK. Therefore the optical measurement system InfiniteFocus is extended with a collaborative robot to automatically pick, place, measure and sort (OK/ not OK) components in production. Watch the video and have a look at the automated measurement solution.
Focus-Variation Technology
Alicona measurement systems are based on the technology of Focus-Variation and combine the functionalities of a surface roughness measurement device and a form measurement system. Each Alicona measurement instrument is a surface measurement device, surface roughness measurement system, 3D measurement system for geometrical tolerancing and micro coordinate measurement system. The Focus-Variation 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. 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.
