UV radiation is invisible to the eye and it is non-ionizing form of radiation in the 100 nm to 400 nm wavelength region of the electromagnetic spectrum. UV radiation is arbitrarily divided into UV-A ...

While Jupiter’s Great Red Spot has been a constant feature of the planet for centuries, a team of astronomers have discovered ...

Photolithography at a wavelength of 193 nm in the deep UV with water immersion lenses can now produce microelectronics containing features with a half-pitch as small as 40 nm. The big question is ...

Extreme ultraviolet (EUV) lithography is the next step in this trend. It uses radiation of wavelength 13.5 nm, thereby offering significant potential to extend the resolution of photolithography ...

The dark UV ovals were first detected by NASA’s Hubble Space Telescope during the late 1990s at the north and south poles.

To understand why, you need a little help from the science you may remember from high school. Light isn’t exactly a wave in ...

Researchers from Japan have developed tuneable blue semiconductor lasers initiating practical far-UV light sources.
