Device, in particular a multiple measurement device, for remote and in situ analysis of a sample by Raman spectrometry

摘要

This device comprises means 2 for producing monochromatic light 4, means 8 for injecting the monochromatic light at a first end 6a of a first optical fibre 6, the second end 6b being situated opposite the sample to be analysed 12, at least one second optical fibre 14, a first end 14a of which is capable of receiving the light re-emitted by the sample 12, a Raman spectrometer 16 for analysing the light re-emitted by the sample, this spectrometer 16 including means 22 for selecting a wavelength of the re-emitted light, this wavelength being characteristic of one of the chemical species making up the sample to be analysed, and means 30 for detecting the selected light signal and converting the latter into a corresponding electric signal. <IMAGE>
