Abstract:
1. A Raman scattering spectrographic analyzer comprising: a microscope having an objective with a field of view adapted to view specimens; means for supporting a substrate having monodispersed-sized metal particles thereon within the field of view of the microscope whereby specimens on one said substrate are within the field of view of said viewer; means for applying a defined wavelength of radiation through said microscope within said field of view and for returning radiation resulting from Raman scattering by specimens within said field of view; spectrographic means receiving Raman scattered radiation from said microscope and operative to provide a signal corresponding to the wavelength components in said Raman scattered radiation; means for analyzing said signal for identification of a specimen within said field of view; and brief case sized carrying means for said analyzer, said carrying means having means to accommodate one said substrate to place one said specimen within said field of view.
