How we measure thin film thickness
Every TDM instrument below is built on the same optical measurement principles. These three guides explain them in detail:
- Thin film thickness — definitions, units, test conditions and the published range of every TDM model.
- How to measure thin film thickness — spectral reflectance, ellipsometry, profilometry and 3D imaging compared.
- Thin film measurement equipment buyer's guide — the three decisions behind any instrument purchase.
