摘要
Absorbing coatings for the HIFI and PACS spectrometers aboard the Herschel platform have been developed and optically characterized. Using radiation from an optically pumped far-infrared laser at wavelengths in the 90 - 900 mum range, the specular as well as the diffuse reflection - characterized by the Bi-directional Reflection Distribution Function - have been determined. The influence of polarization has been addressed too. Moreover, the absorption of non-absorbing diffusely reflecting surfaces, to be used for integrating spheres, has been determined using a low temperature calorimetric method.
