Non-contact Optical Surface Metrology System
The FocusX from Bruker Alicona is a bench mounted 3D non-contact Optical Surface Metrology System providing accurate and traceable form and roughness measurement.
Using the Focus Variation (FV) technique it capitalises on the limited depth of focus by scanning the objective lens vertically and detecting each surface point in focus and building a very high-density 3D topographical map. This provides the ability to measure steep flanks and complex geometries with sub-micron resolution and roughness on those forms. Other techniques such as White Light Interferometry and Confocal Microscopy lack the ability to measure steep flanks and complex geometries.
This technique provides unique geometric measurement capabilities. Using a 5th axis rotation device, it allows the full geometry comprehensive and accurate measurement of cylindrical products such as cutting tools and fuel injection nozzles.
Vertical Focus Probing allows measurement inside bore holes and dimensional position of features. Surface Roughness can be measured with conventional profile-based measurement or with Areal based measurements providing a very accurate and more representative view of the surface based on data point density.
Where CMM tactile measurement methods fail Optical 3D Metrology takes over with users able to measure GD&T features and Roughness parameters robustly and traceably.
Application areas commonly in use include Cutting Tools, Aerospace, Automotive, Medical, Micro & Precision Manufacturing and Electronics both on the floor and in the measurement room.
