Surface Roughness Measurement
In addition to our Form and Difference Measurement solutions, we offer non-contact, high-resolution profile and area-based roughness measurement of surfaces down to 1.2 µinches. Our 3D inspection technology is capable of measuring the surface roughness of almost any material, including metals, ceramics, and plastics.

Profile roughness measurements allow for measurement of both roughness and waviness along an extracted profile to measure roughness values including Ra, Rq, Rz, and many others.
Area based roughness measurements characterize the surface texture of an entire area through the use of surface texture parameters (Sa, Sq, Sz) and bearing area curve parameters (Sk, Spk, Svk).
Through the use of advanced form removal algorithms, roughness parameters can be extracted on complex surfaces including radii, threads, spherical surfaces, and other surfaces with underlying form. This technology allows EDM 3D Metrology Services to measure roughness on complex parts that are otherwise not measurable using traditional surface roughness inspection equipment.
