Device and method for determining a protection factor

Abstract

Described herein is a protection factor evaluation system for determining a protection factor of a skin protection agent with a radiation source with exactly one LED, a detector unit with exactly one photodiode, a control unit and an evaluation unit. Furthermore, the invention relates to a method for determining a sun protection factor of a skin protection agent with the method steps of emitting radiation from precisely one LED of a radiation source, detecting remitted radiation with precisely one photodiode of a detector unit and evaluating the protection factor in an evaluation wavelength range, wherein the protection factor of the protection agent is evaluated from the radiation and a transmission spectrum, and wherein the data of the transmission spectrum for determining the protection factor are in silico and/or in vitro data.
