Calibration method of ultraviolet radiant exposure meters

Ultraviolet radiant exposure meter, also known as UV energy meter, is widely used in a multitude of fields, such as sterilization, climate change, solar photovoltaic, material aging, medical health, UV curing, lithography and so on. Ultraviolet exposure radiation meter is a commonly used instrument to measure ultraviolet radiation. Due to the particularity of the structure and the complexity of the influencing factors, the measurement error of commercial instruments is very high. Commonly used ultraviolet light sources include mercury lamps, LED light sources, metal halogen lamps and so on. This paper will study the calibration method of the ultraviolet exposure radiation meter, and evaluate the measurement uncertainty.
