Abstract

A special multiport UV solar simulator was designed at National Institute of Metrology (NIM), and a set of UVA and UVA+B optical filters were developed to satisfy the spectral distribution specifications of COLIPA SPF and JCIA Persistent Pigmentation Darkening (PPD) test methods. The other purpose of this apparatus is used to calibrate the UVA and UVA+B irradiance or dose of broadband UV radiometers. The response of a double grating spectroradiometer with a 5.8 mm entrance aperture from 250nm to 800nm was calibrated using a 1000W spectral irradiance standard lamp at a distance of 500 mm, and the value of quantities of the developed system is traceable to the national primary standard of spectral irradiance of NIM. The system wavelength was checked using a low-pressure mercury lamp. The spectral response of each port was measured from 250nm to 800nm in 1nm steps. Experiment results showed that the percentage relative cumulative erythemal effectiveness (% RCEE) and UVA measurement waveband values of the multiport UV solar simulator are within the specified limits. The source spectrum is smooth and continuous, and the energy below 290nm is less than 0.1%.
