Optical Interferometry

Optical interferometry is a non-contact measurement technique widely used for high-precision surface and dimensional analysis. Atometrics designs and manufactures white light interferometers and optical interferometry systems that provide accurate 3D surface profiling and roughness measurements.

Principle of Optical Interferometry

Optical interferometry measures the interference pattern created by the interaction of light reflected from the reference surface and the sample surface. By analyzing the fringe patterns, Atometrics systems reconstruct detailed 3D surface topography with nanometer-level accuracy, enabling precise evaluation of surface texture, step heights, and flatness.
