摘要: A technique is introduced for realizing spectral irradiance in the range between 286 nm and 901 nm. The scale based on a temperature-controlled filter radiometer constructed from three-element silicon trap detector, band-pass filters precision aperture. Seasoned FEL-type quartz halogen lamps are used as reference standards. In this method, direct traceability of to cryogenic gives an important advantage visible near-infrared regions. Another system procedure followed measurement distance lamp filament aperture surface radiometer. expanded uncertainty (k = 2) 2.3% 1.5% UV region, while order 0.6% above 400 nm.
