A field test extend blackbody development and application

For performing infrared accurate measurement, It is necessary to calibrate infrared camera and spectrometer equipment field. Nowadays people generally use extend blackbody as standard radiation source. Since the outer environment of low temperature and wind field, blackbody general laboratory used is difficult to meet the requirement of field calibration. Therefore a portable field blackbody is specially developed. The temperature range of blackbody is 50 °C ~200 °C with effective radiation area 200mm×200mm. Using the effective insulation and windproof techniques, the blackbody can work at -20 °C to 40 °C environment. Basically meet the needs of infrared camera, spectrometer and other measuring equipment field calibration.
