In our studio we operate six Raman spectroscopy systems equipped with different laser wavelengths, allowing us to optimize analytical conditions for each specific material. By selecting the most suitable excitation wavelength, we can significantly reduce or overcome fluorescence interference, enhancing spectral clarity and reliability. This flexibility is particularly important when examining complex artistic materials, aged binders, varnishes, and sensitive pigments. Our instrumentation includes both macro-Raman systems for in situ, non-invasive analysis of artworks and micro-Raman microscopes for high-magnification investigation of minute samples and cross-sections. This combined capability ensures precise molecular identification across a wide range of cultural heritage materials.
