  3. Raman Spectrometer (Schematic Setup) laser collecting lens scattered light (Rayleigh + Raman) filter Raman scattered light detector

  4. Raman spectra of green pigments identified as “Scheele’s green” (F) and “Emerald green” (G), two synthetic pigments that were not available in the middle ages. Oops....! Miniature “Susannah” supposedly mediaeval, but made by the “Spanish Forger” in the 19th century Burgio et al., J. Raman Spectrosc. 40 (2009) 2031–2036.
