Yes, Raman can measure film thickness on transparent substrates like glass or polymers. Indeed, Raman spectroscopy can measure anything that respect optical laws. However, the precision is constrained by the diffraction limit, which sets an axial resolution limit of around one micron. Thicknesses below this limit cannot be accurately determined, but for thicker films, precise measurements are possible.
Let's give you more information about that topic below, with a short video answer from our Raman specialist. Go further with related application notes and webinar, or learn more about our solutions for precise measurement of film thickness.
