What to read after CHSOS Application note #5: Reflectance Spectra Database (GorgiasUV Spectrometer) for Pigments Checker “Modern & Contemporary Art”?

Just published on our website the Reflectance Spectra Database for the new Pigments Checker “Modern & Contemporary Art”.

The spectra were acquired with the GorgiasUV spectrometer that covers the extended part of the UV spectrum. This paper discusses these spectra and highlights the most important findings. Used from the late 80′. Reflectance Spectroscopy (RS) is a powerful tool for the identification of pigments and dyes [2]. A reflectance spectrum shows for each wavelength the ratio between the intensity of the reflected and incident radiation. This ratio is called reflectance and is given in percentage (%). Pigments are identified using a spectral database and comparing the spectral features of the investigated unknown spectrum with the spectra available in the database.

The advantages of this method with respect to the other spectroscopic methods are: affordable equipment, small dimension, and portability.
