Surface measurement, also known as surface metrology, refers to the measurement of topography or surface roughness of precision surfaces. Interference microscopy is a non-contact optical profilometry technique used to obtain three-dimensional images and quantitative measurement of surface texture or “roughness.” Surface measurements include surface shape, surface finish, surface profile roughness, surface texture and structural characterization. Surface roughness and the details of the surface profile determine the performance and appearance of many products. The roughness or texture of a part is important for a surface’s suitability in different applications.
