Fast measurements, smooth surfaces and offline measurement planning in CAD
InfiniteFocus G6 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.

Measurement examples with InfiniteFocus G6

Bone screw measurement with roughness profile
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.

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.
