Published on Archeomatica, 1 Marzo 2014 a paper, for Italian readers, introducing the miniaturized spectrometers for Fiber Optics Reflectance Spectroscopy. This paper shows the results of the testing of a FORS (Fiber Optics Reflectance Spectroscopy) system assembled with Ocean Optics components and featuring a USB4000 miniaturized and low cost spectrometer. The small dimensions and little weight of this FORS system make it adapt for the specific needs of art examination in the field. This paper shows the application of this FORS system on a 1800s oil painting and on 1700s Sicilian baroque murals and the results compared with multispectral imaging analysis. A paper in English on e-conservation Journal is soon due to be published with more extensive information and the access to a free database of downloadable FORS spectra of pigments. A brief introduction on the FORS tecquique and this innovative system is in FORS, Fiber Optics Reflectance Spectroscopy for Pigments Identification
