WebAug 1, 2024 · Here tamb()λ is the ambient IR transmission spectrum at AM 1.5 and a water vapor column of 1.0mm [30]. In the study, it is assumed that Tamb is 300K, which leads to IR transmissible window at 8–13µm. To evaluate Eqs. (2) and (3), we use the wavelength range of 3µm < λ < 26µm where most of the black body radiation exists.
