To realize the high accuracy radiance calibration for a ultraviolet detector, a radiance calibration system for ultraviolet detector was established to meet the requirement of ultraviolet remote quantification. On the basis of ultraviolet standard detector in National Institute of Standard Technology(NIST,USA), the absolute criterion was transferred to the responsivity unknown ultraviolet silicon detector, ultraviolet multiplier phototube and the ultraviolet solar blind photomultiplier. The spectral responsivity and quantum efficiency of the ultraviolet silicon detector was calibrated at 200~400 nm and 200~300 nm, and the spatial uniformity was calibrated at 350 nm. According to the guidelines for evaluating and expressing the uncertainty of NIST measurement, the relative uncertainty of transference is less than 2%. Experimental results reported here prove the feasibility establishing a radiance calibration system for ultraviolet detector by a replacement method based on standard detector.
