    摘要: In an optical fittering device comprising at least two fitters, the first filter (EF1) is tilted by an angle of incidence whose value is adjusted to bring the cut-off limit of the first filter (EF1) closer to one of the sides of the line of the illumination beam (FLA), which reduces the optical density of the first filter, while the association in series of the first (EF1) and second (EF2) filters enables to obtain a high-pass filtering whose global density corresponds to the sum of the densities of the first and second filters and whose cut-off limit is lower than that obtained by a single filter tilted to its optimum angle. A third filter (EF3) mounted in parallel with respect to the first and second filters (EF1 and EF2) enables to obtain, at the level of the common collection path (TCC), a band eliminating filtering whose cut-off limits are positioned on either side of the illumination line with a view to an optimum analysis of the low frequency lines.

    摘要: A sample which is exposed to excitation radiation scatters light to a separator filter. The scattered light includes a Raman spectrum. The separator filter reflects, a spectral band of the radiation which it receives and transmits, the remainder of the radiation which it receives. The reflected spectral band is centered on the excitation radiation. The spectral band is collected and guided to a band-eliminating filter in order to eliminate therefrom a spectral band which is narrower than the reflected spectral band, and which embraces the wavelength of the excitation radiation. The band-eliminating filter has a steep elimination slope. A signal corresponding to the reflected spectral band, from which the narrow band has been eliminated in this way, is combined with the radiation transmitted by the separator filter and the combined radiations are supplied to a detection and analysis unit.

    摘要: The spectrometry apparatus of the present invention includes, in addition to conventional analysis, a first diaphragm having a first chosen variable aperture for spatially filtering a coherent-excitation beam. The apparatus also includes a first deflector stage (DF1) for sweeping an excitation beam over a sample according to a first chosen deflection. Additionally, there is included a second diaphragm having a second variable aperture conjugate with the first aperture for filtering the incoherent-scattering beam. The spectrometry apparatus further provides a second deflector stage placed downstream in order to sweep the spectral image of the incoherent-scattering beam thus filtered over the multichannel detection module according to a second chosen deflection.

    摘要: The invention relates to a method of discrimination in spectrometry, particularly of eliminating phenomena of fluorescence in Raman spectrometry. According to the invention, a sample (6) is excited by a luminous pulse (5) generated from a laser (1). The light (7) emitted by the sample (6) is directed into an interferometer (8) of which the duration of a round trip of a luminous ray is significantly longer than the duration of the pulse of the incident wave and shorter than the duration of the phenomenon of fluorescence. The resulting light (9) is then directed to a second interferometer (10) of which the optical path is slightly different from that of the preceding interferometer (8). The light (11) is recovered at the outlet of the second interferometer (10) and this wave is analyzed by means of a spectrometer (12). The invention is applicable particularly to the analyzing of samples in the chemical industry.
