A portable hyperspectral sensor collects reflectance spectra in the range 350-2500 nm, which allows the identification of not only inorganic but also organic materials. In this paper, it was used for non-invasive and non-destructive characterization of pictorial layers in paintings. The results show that their main spectral differences locate between 1200-2400 nm. It is also indicated that when a binder is mixed with colorants, some modifications occur in respect to its original spectrum.

Abstract
A portable hyperspectral sensor collects reflectance spectra in the range 350-2500 nm, which allows the identification of not only inorganic but also organic materials. In this paper, it was used for non-invasive and non-destructive characterization of pictorial layers in paintings. The results show that their main spectral differences locate between 1200-2400 nm. It is also indicated that when a binder is mixed with colorants, some modifications occur in respect to its original spectrum.
