The problem with surface finish is that it gets deep very quickly. Many people talk about the “finish” or the “roughness” of a surface as if it were one unique thing. 

It seems that the subject of 3-D optical surface measurement is all the rage these days.

Reliable measuring results around the clock—this is how TRW Automotive ensures the quality of its steering components down to the sub-micrometer range.

Since the industrial revolution, manufactured surfaces have required analysis to help control metal removal processes like turning, grinding, milling, and more.

Optical profilers using Coherence Scanning Interferometry (CSI) are used in manufacturing to obtain information about both a part’s surface and its gross form.

System integration may seem complex. But the basic process is one that has been ongoing and evolving since a cave man first thought to attach a handle to a rock.
