confocal micro / nano Raman spectroscopy
Confocal Micro/Nano Raman Spectroscopy is a powerful analytical technique that combines Raman Spectroscopy with Confocal Microscopy. It enables the chemical characterization and imaging of materials with high spatial resolution, down to the sub-micrometer range. This technique provides valuable information about the molecular structure, composition, and distribution of components within a sample.
In Confocal Micro/Nano Raman Spectroscopy, a laser beam is focused onto a sample using a microscope objective. The scattered Raman light from the focal plane is collected by the same objective and passed through a pinhole aperture, which acts as a spatial filter, rejecting out-of-focus light from other planes. The filtered Raman signal is then analyzed using a spectrometer and detector, providing information about the molecular vibrations and chemical composition of the sample. By raster-scanning the sample relative to the laser focus, a three-dimensional Raman image can be constructed, revealing the distribution of different components within the sample.
