(redirected from Deep UV)
Also found in: Dictionary, Thesaurus, Medical.


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.
