WebOptical profilers can also measure surface topography of thin films, only if the film thickness and the index of refraction are known. SPM measurements are independent of the properties of the thin film. SPM images taken on a thin film of polycrystalline silicon (unknown thickness) on a silicon substrate are shown in Figures 23 through 26, and the WebJul 30, 2024 · The optical setup is composed of a CMOS sensor with 1936 × 1216 pixels and with a high-speed serial data interface, a specially designed tube lens with specific focal length, which corresponds to a 10 × microscope objective lens yielding a field of view of (1.7 × 1.7) mm and lateral pixel distance of (0.8 × 1.4) μm.

If you need to characterize features at micrometre to sub micrometre on natural or manufactured surfaces, an optical profilometer will provide 3D surface metrology without any – potentially destructive – surface contact. This is a crucial advantage of optical profilometry over tactile (stylus-based) techniques. on my mind by flatt and scruggs
