摘　　要：传统滤光片辐射计在测量紫外(UV)波段时带外泄漏影响严重。将日盲型光电管作为UV滤光片辐射计的探测单元,采用搭建的比对测量装置对日盲型UV滤光片辐射计各通道进行系统级相对光谱辐射功率响应度测量,再利用溯源至中国计量科学研究院(NIM)的光谱辐射照度标准灯对UV滤光片辐射计进行绝对光谱辐射照度响应度定标。采用单色仪系统完成UV滤光片辐射计与溯源至美国国家标准与技术研究院(NIST)的标准探测器的对比,两者结果最大相差2.09%,验证了辐射标准传递的准确性。最后,通过立体角构建,将232~400 nm辐射标准传递到了大口径大动态范围UV积分球辐射源中。The influence of out-of-band leakage on the measurement of ultraviolet(UV)band by traditional filter radiometer is serious.The solar blind phototube is used as the detection unit of the UV filter radiometer,the system-level relative spectral flux responsivity of each channel of the solar blind UV filter radiometer is measured by the built comparison measurement device,and then the absolute spectral irradiance responsivity of the UV filter radiometer is calibrated by using the irradiance standard lamp traced to the Nation Institute of Metrology,China(NIM).The monochromator system is used to complete the comparison between the UV filter radiometer and the standard detector traced to National Institute of Standards and Technology(NIST),and the maximum difference between the two results is 2.09%,which verifies the accuracy of radiation standard transfer.Finally,through the construction of solid angle,the 232-400 nm radiation standard is transferred to the UV integrating sphere radiation source with large aperture and large dynamic range.
