Present and future aerospace systems as well as low-temperature industrial processes require a knowledge of emissivities of materials at extremely low temperatures. Of the several techniques proposed for the measurement of hemispherical emissivities, the use of the boiloff rate of a cryogenic fluid seemed to be the most appropriate. Application of this technique was limited previously by the use of nonblackbody absorbers at the cold plate, and lack of sensitivity of the apparatus.
