| 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.
