MRamanLife Raman microscope is an optical device that conveniently and effectively combines the advanced technological capabilities of a Raman spectrometer and an optical microscope. Such an integrated instrument offers a critical advantage over conventional spectrometers. In this system, the spectral micro Raman signal is collected from a micron-size focal region illuminated by the excitation laser. Therefore, the measurements can be highly localized, which enables spatial scanning across the sample surface, with distinct spectra representing various points of interest.
