A fiber optic measuring system for non-destructive pigment analysis using reflection-Ultraviolet/Visible/Near-infrared (UV/Vis/NIR) spectroscopy and its applicability to 19th century watercolor paintings by Moritz M. Daffinger (1790- 1849) were presented. The spectra obtained by that system enabled the identification of both organic and inorganic pigments without the risk of damage or contamination of the objects analyzed. Evaluation of the measured spectra was carried out using self-built libraries consisting of reference spectra derived from original 19th century watercolor materials as well as materials of the technical collection of our institute (ISTA). Complementary investigations were carried out with reflection-Fourier transform infrared (FTIR) spectroscopy and X-ray fluorescence (XRF). These spectroscopic measurements facilitated the evaluation of UV/Vis/NIR spectra and strongly improved the reliability of the results. The results obtained allowed not only the identification of materials but also statements regarding the specific paint technique of the artist.
