Abstract
Microscopic Raman spectroscopy device that detects and analyzes Raman scattering light emitted from sample irradiated with excitation light includes: laser light source that emits excitation light; spectrometer for measuring spectrum of the Raman scattering light; wavelength discriminator such as a dichroic filter that reflects the excitation light emitted from the laser light source toward the sample and transmits Raman scattering light emitted from the sample toward the spectrometer; condenser lens arranged between wavelength discriminator and the spectrometer for condensing the Raman scattering light passing through the wavelength discriminator; aperture arranged between the condenser lens and the spectrometer for limiting Raman scattering light incident on the spectrometer; adjusting means for adjusting to match a position of spot image of Raman scattering light condensed by condensing lens with a position of the aperture so that light amount of Raman scattering light passing through the aperture is maximized.
