Profilometer is an instrument that measures a surface's profile or roughness at the nanometer level. A contact profilometer has a diamond stylus that physically touches the surface. It is not sensitive to surface color or reflectance. Optical or non-contact profilometers scan the surface with light. A [[confocal microscope]]can be used for characterizing a surface. | |||
