Photothermal - Model IR+Raman -Combined Microscopy O-PTIR and Raman Microscope
The world’s first simultaneous IR+Raman microscopy system is a unique dual modality platform with all the advantages of an O-PTIR microscope combined. That is photothermal microscopy via optical photothermal infrared and Raman combined with a visible probe laser for applications in polymers, defect analysis, microplastic detection and red blood cells. Spectra, line scans and 2D maps can now be collected from the same spot at the same time, opening up new research opportunities and a more thorough characterization of your sample.
Traditionally IR and Raman spectral searching has been done separately and the data has been analyzed separately. Now, with Wiley’s recent release of the KnowItAll multi-technique of simultaneous searching, the hit list information is displayed in a graphical 2D scatter plot. This multi-dimensional approach plots the HQI of the unknown IR spectrum against the HQI of the unknown Raman spectrum dramatically speeding up data analysis. This greatly simplified display of spectral matches in graphical rather than tabular form greatly improves the accuracy of the identification. IR search results can confirm Raman search results and vice-versa, all simultaneously.
