UVblue

UVblue is a term used in several domains to describe concepts related to ultraviolet and blue light. It does not refer to a single, standardized technology or organization, but rather a shorthand used in different contexts to indicate a relationship between UV and blue wavelengths.

In optics and lighting, UVblue commonly denotes systems or materials that operate across the near-ultraviolet and blue portions of the spectrum. This includes sources that emit both ultraviolet and blue light, as well as phosphor-converted LEDs designed to produce spectral content centered in the 380–500 nanometer range. Such configurations are used in curing processes, fluorescence excitation, horticultural lighting, and certain imaging applications.

In fluorescence and imaging, UVblue is used to describe phenomena in which ultraviolet excitation yields blue emission, or where blue-shifted fluorescence is observed under UV illumination. This usage appears in discussions of spectral filtering, sensor design, and fluorescence yield.

In consumer branding, UVblue has been used as a brand or product-name element for coatings, sunglasses, or protective films that claim UV filtration or blue-light management properties. Claims and specifications vary by manufacturer, and the term is not standardized.
