In the world of surface texture, we talk about the size of the features that might impact an application. We use terms like form, waviness, and roughness to talk about

When we think of surface roughness, we often think of machined surfaces. But 3D optical measurement is also essential for controlling much more polished surfaces, such as optical components. Over

3D surface texture impacts friction, wear, and many other functions. In this video we look at 3D surface roughness measurement of automotive engine valves. These small parts have several critical

3D surface texture impacts friction, wear, and many other functions. This video looks at 3D surface roughness measurement of clutch plates. We look at how these surfaces can be tuned

Surface texture on medical devices affects many aspects of performance: how well an implant will bond to tissue, how blood will move over a device without clotting, how well a

We’re excited to kick off a new series of free, in-person seminars covering surface texture measurement, analysis, and application! Seminar 1: Creating surfaces with “high quality” look and feel Join

If you work with precision surfaces, you’ve most likely encountered callouts for surface roughness/surface texture. At first glance, roughness may seem straightforward…you run a roughness gage over a surface, it
