Optical Surface Roughness Measuring Device for Smooth Surfaces
InfiniteFocus G6 is an accurate, fast and universal optical 3D measuring device designed for optical surface roughness measurement & form measurement, particularly for smooth and highly polished surfaces. Operating within the µm and sub-µm range, this device provides precise results regardless of component size, material, geometry, weight, or surface finish, all accomplished with only one optical sensor.
High-Performance Metrology for Complex Measurement Tasks
Unrivaled Measurement Performance
High lateral and vertical resolution combined with high repeatability delivers reliable measurement results — from the finest surface details to complex component geometries.
Groundbreaking User Experience
Fast axes, short measurement times and intuitive operation. From CAD-based measurement planning to single-button solutions, the InfiniteFocus G6 makes even demanding measurement tasks simple and efficient.
Operator-Independent Serial Measurements
Automated measurement sequences ensure consistent workflows and reproducible results—regardless of the operator.
We use the InfiniteFocus G6 to scan tools and analyze various features such as flute shapes, edge rounding on cutting edges, and surface roughness. The system's 3D measurements, area based inspections, and edge master functionalities are invaluable for our work.
