The transmission configuration allows the use of the highest numerical aperture (NA) objectives (including immersion objectives) giving high power density at the focus point and enabling the collection of high signal level, but it can only be used for transparent samples. In 1990 the holographic notch filters were demonstrated to provide superior laser rejection so that a Raman microscope could be built on a single stage spectrograph and provide enhanced sensitivity. Benefits of modern micro-Raman spectroscopy. Probing a large area of the substrate by the mean of a map is often the only way to find the “hot spot” [2, 5]. The relationship between the nominal Raman shift of fiber bundle and the multi-fiber strains was deduced. Transmission Raman is non-contact, non-invasive and non- destructive. In general terms, a Raman spectrometer is integrated with a Raman microscope. 26: A confocal Raman spectral image of 0.9 µm polystyrene beads. Motorized mapping stages allow Raman spectral images to be generated, which contain many thousands of Raman spectra acquired from different positions on the sample. Better yet, it is a label- free super-resolution imaging technique which has been extended by our novel technology into an important new imaging technology. Raman Microspectroscopy. highly specific like a chemical fingerprint of a material. Firstly, the principle and several critical parameters (such as penetration depth, laser spot size, and so on) involved in the Raman characterization are introduced.

In general it is suitable for analysis of: In general it is not suitable for analysis of: Typical examples of where Raman is used today include: Raman spectra can be acquired from nearly all samples which contain true molecular bonding. The difference in energy is made up by a change in the rotational and vibrational energy of the molecule and gives information on its energy levels. E12 - Masao Horiba Awards "X-ray Analysis Technology", Readout No. Micro-Raman spectroscopy continues to be a growing area of research, providing a spatial resolution surpassing that of IR spectroscopy and providing quantitative chemical insight. The principle of Raman spectroscopy was introduced and it was shown that Raman spectra information could effectively reflect crystal structure information of materials. This means that solids, powders, slurries, liquids, gels and gases can be analyzed using Raman spectroscopy. Raman spectra are usually shown in wavenumbers as a shift from the Rayleigh scattered line. When properly designed, Raman microscopes allow Raman spectroscopy with very high lateral spatial resolution, minimal depth of field and the highest possible laser energy density for a given laser power.

It developed as the molecular analog of Castaing's electron microscope. However, since the excitation coincides with UV-visible absorption, fluorescence backgrounds can be significant and more problematic than with ‘normal’ Raman scattering. no sample preparation needed. An alternative approach is Surface Enhanced Raman Scattering (SERS), which offers similar order of magnitude increases in intensity. Micro‐SORS measurements permitted the reconstruction of the layer sequences in selected areas of two 16th century panel paintings, providing unequivocal information about the preparation layer spread over the panels and the pigments used in … E43 - Watching the Environmental and Society with Measurements, Readout No. The Raman spectrum from a material will contain Raman information about all of the molecules which are within the analysis volume of the system. E05 - Semiconductor Instruments, Readout No. Such overlap can result in scattering intensities which are increased by factors of 102-106 – thus, detection limits and measurement times can be significantly improved. The optical coupling that combines the two instruments uses a confocal scheme. In case of complex matrixes, chemometrics methods might also be employed to build quantitative methods. There are several methods in use today (for example, true confocal aperture, or pseudo confocal slit-binning techniques) and some are better than others. False color images can be created based on the Raman spectrum – these show the distribution of individual chemical components, and variation in other effects such as phase, polymorphism, stress/strain, and crystallinity. E08 - Products and Technologies of HORIBA ABX, Readout No. It is based upon the interaction of light with the chemical bonds within a material. The intensity of a spectrum is directly proportional to concentration. Despite the sample being opaque, light from the laser can pass through the sample via light scattering processes. These two cables are connected to a compact, rugged Raman probe head which focuses the laser onto the sample, and collects the Raman signal. E14 - Masao HORIBA Awards"Measurement of Bioparticles" and "Measurement of Internal Combustion", Readout No. Raman microspectroscopy is a technique that uses a specialized Raman spectrometer to measure the spectra of microscopic samples. Two different configurations exist for this coupling: one in transmission and one in reflection (Fig. The difficulty for those experiments is to localise the nanotube on the surface. Typically, a calibration procedure will be used to determine the relationship between peak intensity and concentration, and then routine measurements can be made to analyze for concentration. Raman spectroscopy can be used for microscopic analysis, with a spatial resolution in the order of 0.5-1 µm.

These images show distribution of individual chemical components, polymorphs and phases, and variation in crystallinity. 3: Raman spectra of ethanol and methanol, showing the significant spectral differences which allow the two liquids to be distinguished. Confocal Raman microscopy refers to the ability to spatially filter the analysis volume of the sample, in the XY (lateral) and Z (depth) axes. Raman spectroscopy enables measurement in the low wavenumber region below 400 cm-1, in addition, the NRS-5200 can provide information for the crystal lattice vibration in the very low wavenumber region down to 10 cm-1. Micro-Raman spectroscopy measurements were made on polycrystalline and amorphous thin films of CuInTe 2 as well as bulk polycrystalline CuInTe 2. Transmission Raman is based on the collection of Raman light propagating through the sample in the direction of the excitation laser – in essence, the sample is illuminated with the excitation laser from one side, and the Raman signal is collected from the other. In a proof of principle, the team has collected Raman maps of individual cells from two different cancer cell lines, MIA PaCs-2 pancreatic cancer and Jurkat, T-lymphocytes.
