Ultraviolet Energy

Ultraviolet Energy

Definition

Ultraviolet Energy is the energy carried by ultraviolet (UV) light, which lies just beyond the visible spectrum. This high-energy light can accelerate fading, discoloration, and deterioration of artwork and archival materials.

Characteristics

• Invisible to the human eye but measurable and impactful on materials over time.
• Shorter wavelengths than visible light, giving it higher energy that can break down pigments and fibers.
• Present in sunlight and some artificial lighting sources.

Applications in Framing and Preservation

• UV-filtering glazing, such as conservation acrylic or Optium Museum Acrylic, is used to reduce exposure.
• Conservation framing practices incorporate acid-free and UV-resistant materials.
• Proper display and storage-avoiding direct sunlight and using controlled lighting-help mitigate UV damage.

Best Practices

• Always pair UV-protective glazing with archival matting and backing boards.
• Use blinds, curtains, or museum-grade lighting filters in areas with natural light.
• Regularly rotate or monitor artwork to minimize cumulative UV exposure.
