DESIGNED
High-temperature heater for high-temperature reference points on the basis of metal-carbon eutectic and peritectic compounds, and as reference Planck radiator for reproduction and transfer of unit dimension of Spectral density of radiance (SDR), Spectral density of irradiance (SDI), Light intensity etc.
Also, BB3500M is designed to be used as a temperature heater for high-temperature reference points based on metal-carbon eutectic and peritectic compounds, which are the basis of the temperature scale in the temperature range above 2000 K.
FUNCTIONAL USE
Reference optical source (planck radiator) for reproducing and transfer of unit dimension of spectral density of radiance (sdr), spectral density of irradiance (sdi), light intensity in spectral range 250 – 2500 nm.
USED FOR
Calibration of pyrometers and spectral radiometer, including space basing.
