Apparatus for the Measurement of the Normal Spectral Emissivity in the Infrared

The measuremen t of the spectral emlSSlVl ty of heated substances may be accomplished by comparing the energy emitted by the substance under study 'with that emitted by a standard substance for radiation at various wavelengths. For such a standard one usually uses a blackbody, that is, a hollow body provided with a hole for viewing the radia tion inside. The inside surface of the blackbody must...

Dust Emissivity in the Far - Infrared

We have derived the dust emissivity in the FarInfrared (FIR) using data available in the literature. We use two wavelength dependences derived from spectra of Galactic FIR emission (Reach et al. 1995). A value for the emissivity, normalised to the extinction efficiency in the V band, has been retrieved from maps of Galactic FIR emission, dust temperature and extinction (Schlegel et al. 1998). O...

Infrared pyrometer for temperature measurement of objects , emissivity of which depends on wavelength and time

The multiband MBP 98A pyrometer developed for non-contact temperature measurement of objects with unknown and wavelength-dependent emissivity has been presented in this paper. The pyrometer was designed using single thermoelectrically cooled PbS detector of spectral band of 1-2.5 Ilm and 8 narrow-band optical filters. It enables temperature measurement of objects at temperature within a range o...
