Ultraviolet light occurs between the visible and x‐ray spectrums. The Ultraviolet wavelength range is specified as 10 nm to 400 nm; however, many optoelectronic companies also consider wavelengths as ...
Even though we're warned about the harmful effects of the ultraviolet (UV) rays in sunlight, they're essential for the production of vitamin D in the body. Now, scientists are claiming that UV LEDs ...
For a long time, offset lithographic pressrooms have been reaping the benefits of curing inks and coatings with ultraviolet (UV) radiation instead of drying them with spray powder and/or heat. The end ...
Materials scientists work on the semiconductors that could transform how we disinfect surfaces, spaces, personal protective equipment — even the air we breathe The COVID-19 outbreak brought with it an ...
As Bill Bonallo, president and CEO of IST America, correctly observes, “nowadays, nobody wants to wait for a sheet to dry off press.” But, before the advent of UV (ultraviolet) curing as an ...
Scientists demonstrate the first direct germicidal effect with an ultraviolet LED source. A US collaboration has reduced levels of E.coli. bacteria in water by over five orders of magnitude using 280 ...
ANSAN, South Korea--(BUSINESS WIRE)--Seoul Viosys (KOSDAQ: 092190), a leading compound semiconductor solution provider, announced that its ultraviolet LED Violeds technology – the world’s first UV LED ...
Research published today in Scientific Reports shows that light from RayVio's 293nm ultraviolet (UV) LED is more efficient than sunlight at producing vitamin D3 in skin samples. Tyler Kalajian and his ...
Irvine, Calif. – BivarOpto, the optoelectronics division of Bivar Inc., has launched what are claimed to be the first high-powered ultraviolet light-emitting diodes with typical intensities from 500 ...
