Optical Profilometry Testing
Optical Profilometry Testing Optical Profilometry (OP) or White Light Interferometry (WLI) is an interferometric-based non-contact technology for the measurement of surface topography. It is used to measure surface roughness, coating thickness variation, flatness, surface curvature, texture, and thin-film coating stress. It’s a non-destructive and relatively fast method with a wide range of applications. A diamond stylus is scanned on the sample’s surface in a contact mode profilometer while its vertical movement is recorded. In contrast, a non-contact mode profilometer uses a laser or optical beam. The light beam is split with one half directed to the surface and another half to the mirror. When these beams are recombined, the wavelength scale path difference produced by the topography variations causes interference. Contour information is extrapolated from the interpretation of the interference patterns.
