High-Res, Large FOV…and High Speed, too?

June 17, 2024

3D optical profilers provide high-resolution measurement of surface roughness and shape. Earlier optical profilers were limited by the size of their measurement areas (Field-of-view, or FOV), typically less than 1mm

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!

Average Roughness
