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 ...

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 ...

Ultraviolet light emitting diodes (UV-LEDs) have rapidly evolved as a promising alternative to conventional mercury-based UV lamps in water disinfection systems. Their compact size, reduced energy ...

In a darkened corner of Nanosys's suite here at CES 2025 in Las Vegas was a tiny watch-sized prototype display. At first glance, it didn't seem particularly special. It was bright, for sure, and ...

Published intensity values don’t always reflect real curing performance. Working distance, emitter design, and uniformity can ...

A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical ...

COLUMBUS, Ohio—Commercial uses for ultraviolet (UV) light are growing, and now a new kind of LED under development at The Ohio State University could lead to more portable and low-cost uses of the ...

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 ...

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 are using UV-emitting glass to keep problematic undersea biofilms at bay. The technology may find use in applications such as underwater viewing ports and camera lenses, and perhaps even ...

Muyshondt makes totally over-engineered, no-expense-spared pocket flashlights for camping and other uses, but this one uses an ultraviolet LED made especially for watches — and, more specifically, ...
