The UV spectrum lies between 200 nm and 400 nm and is commonly divided into three regions:UV-A: 320-400 nm; UV-B: 280-320 nm ;UV-C: 200-280 nm .The highest energy region, UV-C is absorbed completely by ozone in the stratosphere. Of the solar UV radiation reaching the earth’s surface, 6% is in the UV-B region and 94% in the UV-A.The potential of UV radiation to cause skin damage rises exponentially with decreasing wavelength. UV light at 280 nm is 1000 times more damaging than light at 340 nm so a fabric’s ability to block UV-B is the most important factor in preventing the negative side affects of sun exposure.
UV Transmittance / Sunscreen Protection Factor Analyzer is an integrated UV spectrophotometer, designed and optimized for the determination of SPF values on a variety of sunscreen and cosmetic products, as well as materials testing. This self-contained, attractive desktop unit reduces the need and associated cost for in-vivo testing.
Many new in-vitro methods for testing sunscreen protection factors are now being embraced by the industry including COLIPA, Boots Star and the FDA. Many of these new methods involve not only testing the Sun Protection Factor (SPF) of a sunscreen, but also the UVA/UVB ray protection of the product.For textile and fabric industries, the demand for accurate measurement of UPF is setting the pace for new global standards.
