AB - DEVICE FOR MEASURING THE EMITTANCE OF SOLIDS AT ROOM TEMPERATURE G. P. Kalugin, S. R. Osmolovskii, and V. A. Chistyakov UDC 681,2 : 536.3 Measurement of the emittance of solids at room temperature is of great scientific and practical importance, for instance, in space and vacuum technology, where it is necessary for calculating the thermal balance of objects under radiative heat exchange conditions, etc. The devices available for this purpose [1, 2], while characterized by small measurement errors, have disad- vantages, such as low efficiency and the necessity for heating the specimens, which leads to errors in determining the surface temperature of heat insulation materials. In practice, quick measurements of large batches of specimens are often performed at room temperature. The many devices available for this purpose, while characterized by low accuracy, secure the necessary speed, for in- stance, the domestically manufactured FM-63 instrument and the device described in [3]. In the FM-63 instrument, the radiation from the specimen is collected by means of a mirror system on the sur- face of a radiation receiver (bolometer), whose temperature is maintained by means of regulators at a level exceed- ing the specimen's temperature by 2-3 deg. A mirror chopper is
