This profilometer works in contact mode. It measures the surface roughness, curvature and step as the sample is moved relative to the contact profilometer’s stylus. As the stylus moves up and down, laser spot move up and down too. A light detector measure laser spot dis-placement.
The minimum step that profilometer can measure is 50 nm and it’s precision is about ±10 nm. The maximum height that it can measure is 100um. Scan line size is 3mm and it can be customized to 10mm or more. profilometer has it’s own software to draw sample roughness and height vs tip position. The whole process is controlled by computer. Our profilometer Can Measure Fast and Easy and Cheap.
We can provide sample test before you buy.
