The S-40-SPF solid state UV spectrophotometer uses technology developed in the last decade to advance the state
of the art of the determination of SPF and UPF values for the sunscreen, cosmetic and textile industries.
Using a high efficiency, long-life LED array combined with an integration sphere coated with a proprietary self-
cleaning, high UV reflectance paint, the system automatically captures spectra and saves the processed data in
multiple formats ( UVPF, SPF, UVAPF, TUV-A, TUV-B, Boots Star rating, and transmission spectra) as well as the
monochromatic protection factor (MPF) for any selected wavelength.
