Optical Surface Roughness Measurement for Accurate Results in One Click

You’re responsible for ensuring surface quality, reliable production results, and efficient processes. You know that surface finish has a direct impact on component performance and overall product quality. But traditional tactile methods often struggle with fine structures or delicate materials.

That’s where optical surface roughness measurement with Focus-Variation comes in: Fast, non-contact, and highly accurate, it delivers ISO-compliant results with one click — no expert knowledge required.
This innovative technology combines precise 3D depth data with true-color imaging, allowing you to analyze even complex surfaces with confidence and repeatability.

Find out how Focus-Variation works, what makes it unique, and how it enhances your surface inspection process.
