Развитие измерений излучательной способности в вакууме в ПТБ
Abstract
The concordance of values of spectral luminance of low and medium temperature standard vacuum blackbodies from the composition of installation for emissivity in vacuum measurements (PTB, Germany) in the range 80 °– 170 °C is considered. It is shown that by means of this installation is possible to measure the spectral radiance at low (up to -100 °C) radiation temperatures in the wavelength range 4,5-20 mkm. The characteristics of the inner coating of the sample spherical enclosure needed at FIR emissivity measurements and for compatibility with vacuum and low temperature conditions are presented.
