Measurement error of radiation gain of UV image intensifier

The radiation gain of UV image intensifier is an important index to measure response capability of ultraviolet detector, thus its accurate measurement is necessary. This paper establishes radiation gain measurement method and device of ultraviolet image intensifier, The process of measuring the magnitude and Influencing factors for the measurement of ultraviolet radiation gain by the equipment were analyzed. And the error analysis of the measurement uncertainty of the device, The radiation gain measurement has an extended uncertainty of 9.59%, It can meet the requirements of high precision measurement of radiation gain of UV image intensifier. The research achievement can support the research and development of domestic ultraviolet detectors, thus providing an effective and accurate detection method for improving and promoting the technical performance of ultraviolet detectors.
