RAMAN SPECTROMETRY APPARATUS

摘要

The invention concerns a Raman spectrometry apparatus comprising an excitation source (14), excitation optical means (16) directing an excitation beam (15) derived from said source on the sample (17), means for collecting (18) energy diffused by the sample (17) including an entrance slit (19) for the diffusion, a spectral dispersion system (20), means for selecting Raman effect energy (23), a sensor (22), optical means (21) for sensing energy directing the collected and selected Raman effect energy towards the sensor (22). The invention is characterized in that the excitation optical means (16) cause the excitation beam (14) to be dispersed by the dispersion system (20), said excitation optical means (16) comprising an entrance slit (24) and an exit slit formed by the diffusion entrance slit (19) and selecting the excitation wavelength.
