Abstract:

An optical pyrometer of the disappearing-filament type was modified to allow brightness temperature measurements to be made in the green region of the spectrum. The modified instrument was re-calibrated at a wavelength of 547 nm. The manufacturers calibration of a second pyrometer operating at lambda 645 nm was verified. Sources of error in the calibrations are discussed. The theory and limitations of two-colour pyrometry as a means of obtaining true source temperatures are presented. Keywords Micro optical pyrometer Two color pyrometry Brightness temperatures Flame temperatures Flame emissivity and Canada.
