The Comparison of Ultraviolet Regular Transmittance
摘要
Abstract
In order to ensure the consistency of UV transmittance values in China with those in the world,the National Institute of Metrology,China,participated in the first research comparison of ultraviolet regular transmittance organized by COOMET during 2018 to 2019.This comparison uses 4 sets of solutions as comparison samples,the nominal value of transmittance covers 5％～90％,and the wavelength range covers 235 nm～350 nm.The comparison results show that the measurement results of each reference laboratory are basically equivalent and consistent.When the transmittance is 50％,the deviation between ours and the international reference value can not exceed 0.12％.When the transmittance is near 20％,the deviation between ours and the international reference value is less than 0.08％.For 10％transmittance,the deviates quantity is no more than 0.03％.关键词
