Abstract

Abstract

The UV LED measurement standard was established to satisfy the high demand for UV LED calibration. The measurement apparatus can measure the optical radiometry parameters (including spectral or broadband irradiance, radiant exposure, spectral or broadband radiant flux, average radiant intensity) of UV LED and UV standard lamps, and further derive the values of peak wavelength, center wavelength, bandwidth, relative spectral distribution, photon flux, photon flux density, external quantum efficiency, and ultraviolet hazards. The UV LED measurement standard adopts a spectroradiometer at primary standard level, as well as the self-designed measurement system and control system. The combined standard uncertainty for 200～450 nm spectral irradiance is 3.3%～0.6%, while the combined standard uncertainty for 200～450 nm spectral radiant flux is 3.4%～0.8%. The establishment of UV LED measurement standard fills the gap in UV spectral radiant flux, significantly improves the measurement uncertainty of UV irradiance, and provides accurate traceability for UV curing and UV disinfection.
