Optical microscope - laser - a microprobe for raman - spectroscopy

摘要

P the invention is of the type comprising means intended to illuminate a sample with a laser, a laser, a microscope providing an enlarged image of the sample, the wavelength selection means of the light reemitted, the detection means of the selected light, characterized by the fact that it comprises means making it possible to obtain an image micrographic, providing the card of the distribution of a species polyatomic data, obtained by a radiation that is characteristic of this species chosen in the raman spectrum stokes or anti - stokes, all the points of the sample being simultaneously illuminated or enlightened successively one after the other, to be illuminated simultaneously along a curve is chosen, these means may also provide either the profile of the intensity of the raman radiation along a chosen curve, which makes it possible to establish a qualitative and quantitative analysis of the species in question, either of the raman spectra of very small localized regions, the choice of the user, in the image of the sample. / p
