New optical 3D profilometer expands SKZ's measurement capabilities

The SKZ Plastics Center in Würzburg has a new non-contact measuring device: Sensofar's S neox optical 3D profilometer enables measurements using confocal microscopy, focus variation and white light inferometry to accurately analyze both ultra-smooth and rough-textured surfaces

Different surfaces can be examined for topography and surface roughness

Optical profilometers are used for non-contact characterization of surfaces with respect to topography and surface roughness. The S neox optical 3D profilometer from Sensofar is now available at SKZ for future surface analysis. It can be used, for example, to evaluate the surface of plastic parts that are used as visible parts in the automotive sector. Surface roughness according to DIN EN ISO 25178 (3D roughness) or DIN EN ISO 21920 (2D roughness) is also of great importance in day-to-day business and can also be determined with the optical profilometer.

Display down to the single-digit nanometer range
The S-neox includes a motorized tip-tilt stage and nosepiece to cover a wide range of surface topographies. The sensor head features focus variation, confocal microscopy and white light interferometry modes. Depending on the operating mode and objective, the profilometer's high vertical resolution allows imaging down to the single-digit nanometer range. Steep edges can be measured up to an angle of 86°, depending on the surface structure. Comprehensive evaluation software completes the measurement system. It can be used, for example, to demonstrate the automated comparison of roughness parameters with process-relevant statistics in SKZ training courses.

Focus on practical learning
"Our focus at SKZ is clearly on practical learning. That's why we attach great importance to good, state-of-the-art equipment. This enables participants in our courses to apply the knowledge they have acquired directly in the company and to bring new ideas back to the industry," explains Matthias Ruff, Sales Manager Education and Research at SKZ.

SKZ offers various quality assurance courses
At the Plastics Center, the optical profilometer is part of the equipment for a number of different courses on quality assurance. Topics include automotive, medical, packaging and quality assurance methodology for various plastics processing methods.
