Abstract
An identification apparatus includes: a plurality of light capturing units including light-capturing optical systems configured to capture a plurality of Raman scattered light fluxes from a sample, an optical fiber unit configured to include a plurality of optical fibers configured to respectively guide the captured Raman scattered light fluxes and in which the optical fibers are bundled at emission end portions thereof; a spectral element configured to disperse the guided Raman scattered light fluxes; an imaging unit configured to receive the dispersed Raman scattered light fluxes; and a data processor configured to acquire spectral data of the Raman scattered light fluxes from the imaging unit and configured to perform an identification process. The Raman scattered light fluxes dispersed by the spectral element are projected so that a spectral image formed on a light-receiving surface of the imaging unit extends along a main scanning direction of the imaging unit.
