Surface metrology involves measuring surface texture, roughness, and topography using contact or non-contact techniques.
Light scattering techniques use the scattered reflection of light from a surface to infer information about the surface texture, structure, and material properties. Techniques include:
A 3D stylus profilometer uses a fine stylus to trace the surface of a part and create a 3D topography map. The stylus moves across the surface in the X and Y directions, while the vertical (Z) displacement is recorded. The resulting data can be used for surface texture analysis, wear studies, and quality control.
Capacitance measurement is a non-contact method to assess surface roughness and other characteristics by measuring the capacitance between a probe and the surface. As the probe moves across the surface, variations in surface topography cause changes in the capacitance, which can then be then correlated to surface roughness parameters. It may be used to measure film thickness…
