Webb27 sep. 2007 · Since chemists are probably the main users of instruments incorporating chemometric methods, for an instrument (or software) manufacturer to give them a term that they're familiar with, to describe a concept that they're familiar with is not an unreasonable decision. Webb1 apr. 2016 · The near-infrared radiation (NIR) window, also known as the "optical window" or "therapeutic window", is the range of wavelengths that has the maximum depth of penetration in tissue. Indeed, because NIR is minimally absorbed by water and hemoglobin, spectra readings can be easily collected from the body surface.
