SWIR Hyperspectral Imaging
Reflectance Imaging Spectroscopy (RIS)
Description
Reflectance spectral imaging is an efficient way of collecting millions of reflectance spectra over an area in one image cube (2D spatial and wavelength in the 3rd dimension). In the SWIR spectral region of the instrument (~1000-2500nm), the spectral features primarily concern overtones associated with molecular vibrational modes, making it sensitive to organic and synthetic materials as well as providing more definitive identification for some inorganic materials. Scanning of a region can be achieved through translation of the object or spectral imaging system via computer controlled XYZ motorised linear translation stages synchronised to the instrument.
