Secrets of household items revealed by coherent Raman microscopy
This project is a part of the Quantitative Chemically-Specific Imaging (qCSI) Infrastructure for Material and Life Sciences, which offers highly advanced imaging technologies for industrial and academic use, in Jyväskylä, Lappeenranta, and Helsinki campuses. In Helsinki, we have constructed a microscope unique to the Nordic countries.
Unlike common light microscopy, our instrument uses so-called coherent Raman spectroscopy, which allows us to visualise the invisible infrared appearance of the sample. The infrared is a much broader and more information-rich spectral region than compared to the visible region we see with our eyes, therefore permitting chemically highly specific imaging.
