The growth and fabrication technology for UV-A LEDs with emission at wavelengths longer than 365 nm is fairly mature. This is a result of their simultaneous development with visible blue-green ...

Carrano says that similar devices operating at a slightly longer wavelength had a lifetime in excess of 100 h and produced many milliwatts of optical power. Covert communicationsAnother application ...

His solution: far-ultraviolet light-emitting diodes (far-UV LEDs). A narrow range of far-UV wavelengths seems to be safe for humans, while being lethal for viruses. Sterilization could become easy, ...

Scientists in Switzerland have developed an ultra-thin metalens that converts invisible infrared light into visible light by ...

A potentially energy efficient and non-toxic alternative is the light-emitting diode, or LED, which can be made to emit at almost any desired wavelength. Ultraviolet light can safely sterilize ...

The entire wavelength range of the UV product series is covered in incremental steps from 5 nm to 25 nm. The company’s two newest UV LED devices operate at 225 nm and 230 nm, respectively ...

As a technology, LED-UV curing for offset printing is slowly, incrementally gaining favor as a method for curing — using intense UV light of a specific wavelength. As one choice among others ...

Kyocera Corporation (President: Hideo Tanimoto, "Kyocera") (TOKYO:6971) has developed a new air-cooled, UV LED light source that ranks among the smallest in its class *1 while providing revolutionary ...

The ultraviolet light wavelengths emitted by this machine are ... ultraviolet light-emitting devices for one 20-minute session led to between 20 and 30 percent cell death, while three consecutive ...
