ULTRAVIOLET RADIATION PROTECTIVE EFFECT EVALUATION METHOD AND DEVICE
摘要
<p>An ultraviolet radiation protective effect evaluation method comprising a first step of measuring the variation with time of a spectral transmission spectrum of a sample under measurement by applying light including ultraviolet radiation from a light source for a predetermined light application time, a second step of correcting the spectral transmission spectrum of the sample under measurement according to the variation with time on the basis of the measurement results obtained at the first step, and a third step of calculating the final in vitro SPF estimation of the sample under measurement by using the correction results obtained at the second step.</p>
