We carry out the calibration of an ultraviolet spectrometer by using a cryogenic electrical-substitution radiometer and intensity-stabilized laser sources. A comparison of the error budgets for the laser-based calibration described here and for a calibration using a type-FEL tungsten spectral-irradiance standard indicates that this technique could provide an improvement of a factor of ~3 in the uncertainty of the spectrometer calibration, resulting in an absolute accuracy (standard deviation of 3) of ~1% at 257 nm. The technique described here might significantly improve the accuracy of calibrations on NASA ozone-monitoring and solar ultraviolet-monitoring spectrophotometers when used to complement present procedures that employ lamps and the SURF II synchrotron ultraviolet radiation facility at the National Institute of Standards and Technology.
我们使用低温电替代辐射计和强度稳定的激光源对紫外光谱仪进行校准。将此处描述的基于激光的校准与使用FEL型钨光谱辐照度标准进行校准的误差预算进行比较表明，该技术可将光谱仪校准不确定度提高约3倍，在257nm处实现约1%的绝对精度（3的标准偏差）。当用于补充目前采用灯以及国家标准与技术研究院的SURF II同步加速器紫外辐射设施的程序时，此处描述的技术可能会显著提高美国国家航空航天局臭氧监测和太阳紫外监测分光光度计的校准精度。
