| 摘要 |
The present invention relates to a method and optical device for Raman spectroscopy and for observing a sample, said device including an optical means for superimposing an excitation laser beam having a spectral band B0 and an observation beam having a spectral band BV so as to form a combined excitation and observation incident beam, and an optical separation means arranged in the path of a collected beam coming from scattering on the sample and including a first filtering means, a second filtering means capable of spatially separating said collected beam into a first secondary beam and two tertiary beams, each of which includes a spectral band selected from the spectral band B0 of the laser, the spectral band BV of the observation beam, and the spectral band BR of the Raman scattering beam, respectively. |
