27 January 2012

In this case study the PerkinElmer® LAMBDA™ 1050 equipped with a 150 mm integrating sphere is used to collect scatter transmission data for sunscreen placed on a tape substrate. Testing sunscreen on a tape model of human skin to calculate the SPF value is shown to be more convenient and economical than testing on human skin.
