Surface metrology involves measuring and characterizing surface textures and features. There are several synonyms that can be used to describe this field, including surface roughness measurement, surface profilometry, surface topology analysis, and surface finish analysis. These terms all refer to the measurement and quantification of surface characteristics such as roughness, waviness, and flatness. Surface metrology is a critical field in industries such as manufacturing and engineering, where the surfaces of components and products must meet exacting specifications for performance and quality. Accurate measurement and analysis of surface features can help ensure that products perform as designed and meet customer expectations.
