      abstract = {Optical absorption spectroscopy of individual tissue  components is commonly used to identify optimum wavelengths  for noninvasive light-based physiological monitoring.  However, absorption spectroscopy has historically covered  primarily the VIS and NIR wavelengths ranging from 400 to  1,000 nm. This limitation was primarily due to hardware  lacking sensitivity at longer wavelengths. Hardware  advancements in the SWIR range have enabled investigators  to explore the SWIR wavelength range, from approximately  1,000 nm up to 3,000 nm. This region has characteristic  absorption peaks for lipid, protein, and water, which are  difficult to visualize in the VIS-NIR and can provide  label-free sources of biological contrast. Additionally,  melanin, the primary chromophore responsible for skin  pigmentation, has lower SWIR absorption. Researchers have  found that in vivo optical devices like clinically standard  pulse oximeters may have reduced accuracy in people with  darkly pigmented skin because they do not account for  stronger melanin absorption in the VIS and NIR range. Thus,  devices operating in the SWIR could significantly reduce  error due to skin pigmentation. Understanding the  absorption properties of core tissue components from the  VIS to the SWIR range is vital for effective optical  instrument design. These datasets provide detailed  absorption values spanning the VIS to the SWIR of the  following common tissue absorbers: oxygenated hemoglobin,  deoxygenated hemoglobin, melanin, water, and lipids. },
