(redirected from Near-ultraviolet)
Also found in: Dictionary, Thesaurus, Medical, Acronyms.


the part of the electromagnetic spectrum with wavelengths shorter than light but longer than X-rays; in the range 0.4 × 10--6 and 1 × 10--8 metres


Pertaining to ultraviolet radiation. Abbreviated UV.


(1) See ultraviolet light.

(2) A cloud-based storage locker for licensed content from the Digital Entertainment Content Ecosystem (see DECE). Under the Digital HD brand, purchases of Blu-ray discs with redeemable coupons and purchases of movies and TV shows (not rental) from participating online retailers entitles users to keep their content in the UltraViolet cloud and stream or download it as required.

Depending on the retailer's agreement, content might be sharable with friends and family, and parental access can be applied. A physical disc may also be obtainable. See Digital HD, Blu-ray Combo Pack and media locker.

The near-ultraviolet observations offer another advantage.
GALEX is doing this by acquiring images in two ultraviolet bands: a far-ultraviolet channel that transmits light with wavelengths near 150 nanometers, and a less energetic near-ultraviolet band centered at 230 nm--across a 1.
Sabeus scientists, however, engineered a new system where a longer wavelength of near-ultraviolet light is used to "cold write" the fiber core right through the cladding and the protective polymer.
Northwestern University's LRO Camera consists of two narrowangle cameras with half-meter resolution for landing-site imaging and one wide-angle camera with 100-meter resolution, which will complement the Clementine spacecraft's old green-to-infrared lunar maps with new blue and near-ultraviolet ones.
