SpletShortwave infrared (SWIR) fluorescence imaging is a tool for visualizing biological processes deep within tissue or living animals. Our study shows that the contrast in a SWIR fluorescence image is primarily mediated by the absorptivity of the tissue, and can … Shortwave radiation (SW) is radiant energy with wavelengths in the visible (VIS), near-ultraviolet (UV), and near-infrared (NIR) spectra. There is no standard cut-off for the near-infrared range; therefore, the shortwave radiation range is also variously defined. It may be broadly defined to include all radiation with a wavelength of 0.1μm and 5.0μm or narrowly defined so as to include only radiation between 0.2μm and 3.0μm.
