Optical Surface Roughness Tester

An optical surface roughness tester is a precision instrument designed to evaluate the micro-topography and texture of surfaces without physical contact. Atometrics develops advanced systems based on optical interferometry and focus variation, providing highly accurate roughness measurements for industrial and research applications.

High-Precision Non-Contact Roughness Measurement

Unlike traditional stylus testers, Atometrics’ optical surface roughness tester captures detailed 3D surface data using light interference and imaging analysis. This non-contact method ensures no surface damage while achieving nanometer-level vertical resolution, enabling accurate characterization of Ra, Rq, Rz, and other surface parameters.
