SharpEyeTM IR3 Flame Detector User Guide 2.2.3 Limitations of IR-IR Flame Detectors CO2 in the atmosphere attenuates the radiation in this spectral band. (Absorption and emission of radiation always occur in the same band.) As a result, the greater the distance between the detector and the fire, the weaker the intensity of the radiation reaching the detector (the CO2 attenuation increases). This phenomenon explains the limitations of the existing IR-IR flame detectors in the market: 2.2.
