The development of emissivity measurements under vacuum at the PTB

Measurement Techniques Aims and scope

The consistency of the values of the spectral radiance of two standard vacuum absolutely black bodies (low and medium temperature) in the 80–170°C range, forming part of the equipment for measuring emissivity under vacuum, is considered. It is shown that, using this equipment, one can measure spectral radiance at low radiation temperatures (down to –100°C) in the 4.5–20 μm wavelength band. The characteristics of the inner coating of the sample enclosure, required in order to make the measurements in the far infrared band and compatible with the vacuum conditions and low temperatures, are presented.
