Applications of a Compact Portable Raman Spectrometer for the Field Analysis of Pigments in Works of Art

摘要

The importance of Raman micro-spectroscopy for the identification of pigments in works of art is well established. In recent times, portable Raman spectrometers have been introduced which allows users to perform field analysis directly where the artefacts are placed (churches, museums, archaeological sites, etc.). The present work reports results obtained by a remarkably compact instrument, in particular, on frescoes and illuminated parchments.
