Abstract
A method of calibrating low-intensity spectral irradiance using a mesh attenuator and a 500-W spectral irradiance standard lamp has been developed. The intensity of the lamp's irradiance is the same as that of a 20-W spectral irradiance standard lamp. The photometric value of the 500-W lamp stabilizes (±0.04%) within 15 min. of being turned on. In testing, the reproducibility of the photometric value for the mesh attenuator and detector setting was ±0.07%. The stray light under indoor illuminant was under 0.002% of the photometric value. The uncertainty of this calibration system was less than when using a 20-W spectral irradiance standard lamp.
