Abstract
The invention relates to a Raman spectrometer connected by a bundle of optical fibers with an external probe to be attached on the surface of the sample with a laser beam for the excitation of Raman radiation within the sample with the laser radiation transported to the sample by one or several central optical fibers and with a collecting element which collects the Raman radiation of the sample and sends it through the optical fiber bundle to a Raman spectrometer to be analyzed. Upon the end of the optical fiber bundle different collecting elements may be attached with the transparent optical elements having the shape of a cylinder, a paraboloid or a truncated sphere. Thus, the spectrometer can be simply adapted to different samples for optimal collection of Raman light.
