<P>PROBLEM TO BE SOLVED: To improve accuracy of measurement. <P>SOLUTION: A Raman spectroscopy device (1) comprises: excitation light sources (11) for generating excitation light for excitation to be emitted to a measurement object (15); a fiber bundle (3) that consists of a plurality of optical fibers through which light can be transmitted and has incident units (21) on which Raman light from the measurement object (15) is made incident and an emission unit (22) from which the Raman light is emitted; a spectral unit (28) for spectrally separating the Raman light; and a detector (31) for receiving and detecting the light beams resulting from the spectral separation. In the emission unit (22), other ends of the optical fibers are arranged on an arcuate line on the basis of an elevation angle (γ) of the light made incident on the spectral unit (28). <P>COPYRIGHT: (C)2012,JPO&INPIT |
