12 Nov 2012 With the increasing need to ensure that our skin is protected from harmful UV rays, the SPF-290S is a valuable tool. It is a recording UV spectrophotometer designed specifically to establish the SPF (sun protection factor) values of a large range of sunscreens and cosmetic products, thus significantly reducing the need for in-vivo testing.
The system automatically scans from 290nm - 400nm, gathering and storing the data at intervals of 1, 2 and 5nm. Using solar irradiance and erythemal constants that are programmed into the software the monochromatic protection factor (MPF) is determined for each of the selected wavelengths and is used to calculate the SPF value.
Available with a variety of accessories and upgrades the SPF-290S Analyser System is an exceptional tool supplied by LASER COMPONENTS, partners and distributors for OPTOMETRICS CORP.
