S-40-spf integrated system

system-UV Penetration and Protection Measurement-S-40-SPF-01-Resonance


The S-40-SPF solid state UV Penetration and Protection Measurement System 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
