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.

An improved capacitor roll with alternating film and foil layers is impregnated with an adhesive, elastomeric gel composition. The gel composition is a blend of a plasticizer, a polyol, a maleic anhydride that reacts with the polyol to form a polyester, and a catalyst for the reaction. The impregnant composition is introduced to the film and foil layers while still in a liquid form and then pressure is applied to aid with impregnation. The impregnant composition is cured to form the adhesive, elastomeric gel. Pressure is maintained during curing.
