IR+Raman/IR plus Raman

Same spot.

Same resolution.

Same time.

Simultaneous, submicron IR and Raman microscopy
O-PTIR and Raman microscope combined

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.

Simultaneous IR and Raman spectral searching, complementary and confirmatory

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.

Unlocking new applications

O-PTIR combined with Raman can be applied to applications in polymers, defect analysis, microplastic detection and red blood cells

Simultaneous submicron IR and Raman microscopy – A world first

Optical photothermal infrared and Raman combined surpasses accepted limitations of IR microscopy, ushering in a new era of analytical capabilities and problem solving. Coupled with simultaneous Raman microscopy, IR+Raman is now finally possible! This webinar discusses O-PTIR and its major benefits across a range of application areas, including defect and failure analysis, polymers, materials, life science, pharmaceuticals and forensics.
