Blackbody source in the -50 to +200 degrees C range for the calibration of radiometers and radiation thermometers.
A high-accuracy, large-aperture calibration source for radiometers and infrared radiation pyrometers operating in the range from -50 to +200 degrees C is described. It is shown that by means of reflecting surfaces inside the blackbody the requirements for temperature uniformity can be substantially relaxed while high accuracy in the characterization of the effectivet emperaturei s maintained.
