Bolometer

Inventia se refera la receptoare cu racire pentruradiatie infrarosie si poate fi aplicata in spectroscopie, radiometrie, geofizica si astrofizica. Bolometrul contine un criostat de heliu (1) in care este amplasat un element sensibil supraconductor(2) la care este conectat un dispozitiv de inregistrare (4). Noutatea inventiei consta in aceea ca in criostat (1) este amplasat un regulator de temperatura (3), iar elementul sensibil supraconductor(2) este executat dintr-un semiconductor, de exemplu, din telurura de plumb dopata cu taliu Pb1-xTlxTe, unde x = 0,01...0,0225. 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 = 0,01...0,0225.
