分光辐射计与辐射计对紫外辐射测量的对比

Spectroradiometers and broadband radiometers, although quite different in their principles and purposes, are often used to perform the same task of monitoring biologically effective UV exposure. In this work we focus on the performance analysis of both types of instruments for this particular task, bearing in mind, that where the spectral resolution of irradiance is needed the spectroradiometer is essential. On the other hand, biologically effective dose is best measured with a radiometer. The complexity of the spectroradiometer makes preferable the convenient broadband instrument where spectral resolution is not required. Relevant specifications for both types of instruments are presented and their impact on the measurement process discussed.
