LEDs emitting light in the range of 200 nm to 400 nm are classified as UV LEDs. Within this range, there are three bands, UV-A with wavelengths from 300 nm to 400 nm, UV-B with wavelengths between 280 ...

And just like that, it’s dry. In mere milliseconds, UV ink, when exposed to intense UV light, transforms from a liquid to a solid state. With this reality comes opportunity for those using sheetfed ...

This engineer doesn’t use nail polish, but his wife does. And he deals with plenty of PCBs. What do these things have in ...

Despite the potential hazards of ultraviolet (UV) light that are evident in everyday life, such as sunburn, the UV spectrum offers many benefits in a multitude of areas. Not unlike how standard, ...

Germicidal lamps are designed to destroy viruses and bacteria using ultraviolet light. But not just any UV light will work, and I came across an example of a lamp that was advertised as germicidal but ...

Conventional deep UV LEDs (below 275nm) have long frustrated system developers with poor reliability, inefficient power consumption and suboptimal wavelength control – creating a technical ceiling for ...

Biomolecular contaminants dislike the spotlight, especially if it’s an ultraviolet (UV) spotlight. So, biomolecular contaminants must really hate the intense glare from decontamination systems that ...

In tests conducted with Yamaguchi-University, Stanley Electric has achieved 99.9% ‘inactivation’ of Covid-19 virus SARS-CoV-2 using its aluminium nitride-based 265 nm UV-C leds. Inactivation here, ...

Toward standardization of inactivation evaluation. Nichia develops a UV irradiant device to evaluate UV sensitivity for inactivation evaluation of microorganisms. The LED characteristics and design of ...

Ledil has designed a family of optics for domed UV leds. Called G2-Rose-UV, they are “UV-resistant with no notable decrease in light transmission rates”, said the firm. Made of silicone, they “can be ...
