Stamps are cultural heritage objects that provide an invaluable amount of historical information. There is an increase of counterfeit historical inks and it is imperative that fraudulent stamps can be identified and removed from the market. The portable Raman i-Raman EX® with a 1064 nm laser is used because it minimizes the fluorescence of the ink. The i-Raman EX® also has the functionality of low laser power reduction down to 1% to prevent sample burning and the Raman video microscope system analyzes the smallest of details, which is imperative for cultural heritage analysis of an 1885 historical envelope.
