Hyperspectral imaging in the mid-IR provides for the chemical identification of both organic and inorganic materials and their spatial, macro-scale distribution
The portable imager accesses the largest IR range never explored in the mid infrared imaging (4000-800 cm-1) performing spectrally and spatially resolved molecular spectroscopy at the macro-scale. It provides information concerning the functional groups constituting the molecules ultimately aiding a molecular identification of unlimited materials under exam. The mid-IR range is particularly adapt for the recognition of inorganic materials (with limitations from metal oxides) as well as synthetic and natural organic materials. This technique can provide information concerning any surface contaminations, alterations and products/processes of degrade. The surface sensitivity of this method makes it an invaluable tool for identifying surface layers or applications (e.g., varnish, coating), visualizing their distribution, and monitoring their removal in real-time during cleaning operations.
