| 摘要 |
The invention relates to the cooled infra-red radiation detectors and may be used in spectroscopy, radiometry, geophysics and astrophysics. The bolometer contains a helium refrigerator (1), wherein it is installed a superconductive sensing element (2), to which it is connected a recording device (4). Novelty of the invention consists in that into the refrigerator (1) it is placed a temperature control (3), and the superconductive sensing element (2) is made of a semiconductor, for example, of lead tellurium doped with thallium Pb1-xTlxTe, where x = 0,01à0,0225.
