However, a new formula protects against both UV light and heat from the sun using radiative cooling. The prototype sunblock kept human skin up to 11 degrees Fahrenheit (6 degrees... Read more
it would have to be made of a fabric with a band pass filter that blocks all wavelengths EXCEPT UV. Not impossible, but not a thing yet. As far as I know. Could be dangerous though, folks will be getting blasted by UV all day long without realising it. So there’s your cancer versus vanity gamble.
PIXELTEQ’s ultraviolet (UV) optical bandpass filters deliver precise transmission of specific UV spectral bands while blocking out-of-band signals at higher and lower wavelengths. The multi-edge bandpass filters transmit wavelengths defined by a nominal center wavelength (CWL) and bandwidth (FWHM ... Read more
Is a material like this possible? ” A lot of materials will not allow visible light through but will allow UV through, as UV is more powerful, just as X-rays can get through your muscles to your bones but visible light can not as easily.” – but no examples given.
