Abstract EN
Anew mathematical formula was proposed to describe the behavior of the extinction coefficient as a function of ambient temperature and wavelengths for some of infrared materials.
This formula was derived depending on some experimental data of transmittance sp ectrum versus wavelengths for many ambient temperatures.
The extensive study of the sp ectrum characteristics and depending on Bose-Einstein distribution led to derive an equation connecting the extinction coefficient or the absorption coefficient with the ambient temperature and wavelengths of the incident rays.
The basic assumption in deriving process is the decreasing in transmittance value with the increasing temperature which is only due to the changing in extinction coefficient values.
