Profilometer
A profilometer is a measuring instrument used to measure a surface's profile, in order to quantify its roughness & the thickness of thin film samples. Critical dimensions as step, curvature, flatness are computed from the surface topography.A typical profilometer can measure small vertical features ranging in height from 10 nanometres to 1 millimetre. The height position of the diamond stylus generates an analog signal which is converted into a digital signal, stored, analyzed, and displayed. The radius of diamond stylus ranges from 20 nanometres to 50 μm, and the horizontal resolution is controlled by the scan speed and data signal sampling rate. The stylus tracking force can range from less than 1 to 50 milligrams. For more details please follow the link

Alpha -Step D-600 |
Working Principle |
A diamond stylus is moved vertically in contact with a sample and then moved laterally across the sample for a specified distance and specified contact force.The profilometer can measure small surface variations in vertical stylus displacement as a function of position. |
