Dimensional accuracy & surface finish measurement

NEW: InfiniteFocusG6

InfiniteFocusG6 is an accurate, fast and universal optical 3D measuring instrument for tolerances in the µm and sub-µm range. Components are measured area-based and with high resolution independent of size, material, geometry, weight and surface finish. A number of proven and new features combine the functionalities of a roughness measuring system (Ra, Rq, Rz/Sa, Sq, Sz) with the characteristics of a coordinate measuring machine.

InfiniteFocus is ideal for manufacturing. The robust Focus-Variation technology and the vibration-insensitive design ensure high-resolution and repeatable results, even directly next to the machine tool.

Webinar: 3 technologies in 1 sensor - faster, more intuitive and more accurate with InfiniteFocusG6

In our upcoming webinar on May 31, you learn everything about our brand new 3D metrology system - from advantages to applications.

The brand new InfiniteFocusG6 stands for:

- UNRIVALED MEASUREMENT PERFORMANCE -

- GROUNDBREAKING USER EXPERIENCE -

- FUTURE-PROOF TECHNOLOGIES -

- SMART DESIGN -

A number of proven and new features combine the functionalities of a

roughness measuring system with the characteristics of a coordinate measuring machine:

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.

SmartFlash & Real3D:
The integrated SmartFlash technology ensures high-resolution measurement of smooth, reflective and highly polished surfaces. Real3D turns individual measurements into a complete 360° data set.

MetMaX user software:
Users specify measurements already in the CAD model of a component. A Digital Twin combined with a virtual measurement simulation enable safe operation of the measuring instrument.

Vertical Focus Probing:
The latest technology enables the optical, lateral probing of components. Users measure holes and vertical flanks (>90°).

Measurement examples with InfiniteFocusG6:

Smooth surface

Thanks to Advanced Focus-Variation, users measure workpieces with steep flanks, varying reflections and structured roughness. The integrated SmartFlash technology ensures high-resolution measurements of smooth, reflective and highly polished surfaces.

Bone screw

By applying Real3D technology, users achieve full form measurements of a component (360°). Here, a direct comparison to the respective CAD data set is shown. In addition, roughness can be measured.

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.

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.

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 - Automated placing & measurement of components

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.
