Microscopic Raman spectroscopy device and method for adjusting microscopic Raman spectroscopy device

A microscopic Raman spectroscopy device that detects and analyzes Raman scattering light emitted from a sample irradiated with excitation light, the microscopic Raman spectroscopy device comprising:

• a laser light source that emits the excitation light;
• a spectrometer for measuring a spectrum of the Raman scattering light;
• a wavelength discriminator of light that reflects the excitation light emitted from the laser light source toward the sample and transmits the Raman scattering light emitted from the sample toward the spectrometer;
• a condenser lens arranged between the wavelength discriminator of light and the spectrometer for condensing the Raman scattering light passing through the wavelength discriminator of light;
• an aperture arranged between the condenser lens and the spectrometer for limiting the Raman scattering light incident on the spectrometer;
• at least one movable mirror configured to adjust and match a position of a spot image of the Raman scattering light condensed by the condensing lens with a position of the aperture so that a light amount of the Raman scattering light passing through the aperture is maximized.
