Temperature dependence of factor of absorption efficiency of thin-wire platinum bolometer

摘要

The correct use of classical optic long-wave approximation or a complex refraction index for platinum on radiation wavelength 10.6 μm is shown. The factors of absorption efficiency of platinum conductors with the diameters of 3, 10 and 20 μm in dependence on temperature were calculated. It was ascertained that the diameter of a conductor does not influence on normalized temperature dependence of the absorption efficiency factor.
