Abstract
A Raman probe includes: a first illuminating fiber and a second illuminating fiber that are arranged in series and that are formed of different materials from each other; a coupling optical system for optically coupling the first and second illuminating fibers; a light-collecting fiber that is formed of the same material as the second illuminating fiber and that collects Raman scattered light from an examination subject; and an optical filter that is disposed between the first and second illuminating fibers and that selectively transmits a laser beam being guided by the first illuminating fiber and, of Raman scattered light of the first illuminating fiber excited by the laser beam, Raman scattered light the amount of Raman shift of which is smaller than a predetermined amount of Raman shift in a Raman spectrum of the examination subject.
