Abstract: The LVARS is a fully instrumental, non-destructive spectroscopic device for the analysis and verification and authentication of the optical and electromagnetic properties (OEMP) of the inks, dyes, thin films, plastics, toners, paper, fixatives, paints, and printing agents used in documents and financial instruments. The instrument is quantitative in nature so as to correlate compositional data (elemental, isotopic, structure) with Raman optical spectra. The LVARS design consists of a computer-controlled spectrometer with a microscope-guided grid head containing the laser excitation source and detector and optics.

Abstract: The LVARS is a fully instrumental, non-destructive spectroscopic device for the analysis and verification and authentication of the optical and electromagnetic properties (OEMP) of organic or inorganic media that is either naturally occurring, or manufactured or processed such as the inks, dyes, thin films, plastics, toners, paper, fixatives, paints, and printing agents used in documents and financial instruments. The instrument is quantitative in nature so as to correlate compositional data (elemental, isotopic, structure) with Raman optical spectra. The LVARS design consists of a computer-controlled spectrometer with a microscope-guided grid head containing the laser excitation source and detector and optics. The spectrometer contains signal processing electronics which sends a stream of data to the computer for analysis and correlation with the library database.
