ABSTRACT:
An optical Raman microprobe with laser excitation for illuminating a sample, comprising means for illuminating the sample with a pulsed or continuous laser radiation of selected frequency, a microscope furnishing an enlarged image of the sample, means for selecting the wavelengths of the re-emitted or scattered light and means for detecting the selected light. The microprobe further comprises means for obtaining a micrographic image of the sample, to provide a map showing the distribution of a selected polyatomic species in the sample, by isolating a radiation characteristic of such species in the Raman, Stokes or anti-Stokes spectrum. All points of the sample may be illuminated simultaneously, or successively one after the other, or simultaneously along a selected line or curve. The apparatus may furnish the intensity curve of the Raman radiation along a selected straight line or curve, which permits a qualitative and quantitative analysis of the species selected, or it may furnish Raman spectra of very small, localized, selected regions within the image of the sample.
