Zusammenfassung: | FIELD: physics. ^ SUBSTANCE: device consists of a cylindrical vacuum chamber in which there is a cooling screen, material test specimen with a heater, fixed on a rotating suspension, and an optical measuring system, consisting of a monochromator, modulator, infrared lenses and a radiation receiver. The sample is heated either by infrared radiation or by electrical current due to ohmic resistance. ^ EFFECT: measurement of angular dependencies of spectral ratios of radiation. ^ 2 dwg |
