A profilometer/roughness gauge is a measuring device used to capture 2D or 3D data on the surface of a sample in order to measure roughness, flatness, or other critical 2D and 3D dimensions.

What is the purpose of profilometer?

Profilometry is a technique used to extract topographical data from a surface. This can be a single point, a line scan or even a full three dimensional scan. The purpose of profilometry is to get surface morphology, step heights and surface roughness.

What is profilometer metrology?

A surface profiler/profilometer is a metrology instrument for topographical characterization of a product's uppermost layers.
