Optical absorption water lipid
WebNational Center for Biotechnology Information Webmophores and water have relatively low absorption coeffi-cients but high effective scattering coefficients [12]. In addition, numerous tissue chromophores, such as hemoglo-bin and fat, have a unique absorption spectrum in this region [13]. Compared to an optical window, the absorption rate of water in the spectral region is less than 700nm.
