| Outline of Final Research Achievements |
Evaluation of sub-surface layer is has attracted attention with development of film formation technology. Raman scattering spectroscopy is one of the powerful technique for evaluating the surface layer. Raman scattering spectroscopy has the advantage that it can measure non-destructive and non-contact, and it is possible to identify of molecular structure and chemical bonds. On the other hand, in a sample transparent to the excitation light, excitation light reach into the inside of the sample, so it is difficult to acquire only the Raman signal form the surface layer. In this research, we have constructed a Raman scattering spectroscopy system using an entrance / collection optical system consisting of multiple spheroid mirrors.For verification of the optical system, it was possible to measure the samples with known spectra such as diamond and clearly observe those spectra.
