3D Surface Roughness and Wear Measurement, Analysis and Inspection
Are you relying on average roughness (Ra) to control your surfaces? We made this short animation using data from Digital Metrology Solutions, Inc. to show that very different surfaces can all have the same Ra value...and that Ra alone can't tell you which one you've manufactured!

What are the 3D optical profiler measurement modes?

February 26, 2024

In the early days of 3D optical profiling, we needed to know an “alphabet soup” of measurement modes in order to operate the systems. Smooth surface? That’s one mode. Rougher
