Abstract

Micro-Raman spectroscopy is excellently suited for the investigation of artifacts, as it is a fast and nondestructive method that can be applied for the identification of a whole range of materials. This identification depends on spectrum interpretation and on the comparison of the unknown spectrum with an extended library. Another advantage of Raman spectroscopy is that spectra can be recorded by direct analysis of the artifact or of micro- samples. The coupling of the spectrometer with a microscope reveals a high spatial resolution, which allows spectra of individual grains with dimensions down to 1 micrometers to be recorded. Therefore a non-destructive micro-sampling method can be used. Raman spectroscopy can be applied for several types of materials and is applicable to ancient pieces as well as modern objects of art. An example is given on the Raman spectroscopic examination of miniatures from a medieval book of hours and of a 19th Century porcelain card.
