Optical Raman microprobe with laser

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