建立了一个绝对辐射标准，用于200年至2000年μ之间。结果表明，在此波长范围内，输出为黑体的输出。用绝对标准校准了等值温度在3000°K附近的二级标准汞弧灯。结果表明，绝对标准既可用于直接测定未知信号的强度，也可用于校准单色仪-探测器系统的灵敏度。
An absolute radiation standard is constructed for use between 200 and 2000 μ. It is demonstrated that the output is that of a blackbody over this wavelength range. The absolute standard is used to calibrate a secondary standard mercury-arc lamp which is found to have an equivalent temperature in the neighborhood of 3000°K. It is shown that absolute standards can be used either to determine the strength of an unknown signal directly or to calibrate the sensitivity of a monochromator-detector system.
