Spectral Absorption Curves
The following spectral absorption curves show the range of wavelengths that a particular material will absorb infrared radiation as well as the percentage of absorption. These curves are only representative of a particular sample of a given "virgin" material. In actual practice, coloring agents and other additives will change the look of the curves. However, the curves can be used to get a general idea of the range of infrared radiation in which the material will absorb.
