摘　　要：对WGD-8A型组合式多功能光栅光谱仪进行改造,设计样品槽及与其配套的样品池,放置于多功能光栅光谱仪的光源和入射狭缝中间.选择紫外灯作为光源,测量了不同SPF及不同PA的防晒护肤品的透光率,并研究了不同暴晒时间防晒护肤品的隔离效果.The WGD-8A multi-functional grating spectrometer was modified.The sample tank and its matching sample pool were designed,which would be placed between the light source and the incident slit of the multi-functional grating spectrometer.UV lamp was selected as the light source to measure the transmittance of sunscreens with different SPF and PA,and the isolation effect of sunscreens with different exposure time was studied.

关 键 词：多功能光栅光谱仪 透光率 光谱测量
