Description: Profilometry is a fast and direct method for measuring step heights, surface roughness, etching depths and planarity.  A diamond stylus is placed in contact with a sample and moved laterally across the sample for a specified distance and contact force.   The height position of the diamond stylus generates an analogue signal which is converted into a digital signal stored, analysed and displayed.
