Art Restoration UVA Lamp Technology: Illuminating the Hidden History of Artworks

In the art world, the value of a masterpiece is determined not only by its aesthetic beauty but also by its history, origin, and integrity. Understanding the true story of artworks that have changed hands, been restored, or altered over centuries is a major challenge for experts. In this complex process, modern technology has become the most powerful ally of art historians and restorers. Specifically, art restoration UVA lamp technology is revolutionizing authentication and conservation work by illuminating the hidden layers of artworks.

The Detective Role of UVA Light in Art Examination

UVA (Ultraviolet A) light is a special wavelength invisible to the human eye, but it causes certain substances to glow (fluoresce) under its light. When used on artworks, this fluorescent property provides invaluable clues to art historians and restorers:

Detecting Overpainting and Repairs: Old paintings are often repaired due to cracks or damage over time. Modern paints and varnishes used during restoration show different fluorescent properties than the original materials of the artwork. Under an art restoration UVA lamp, these repair areas, which fluoresce differently from the original surface, can be easily detected. This allows for an understanding of how much of the work is original and what kind of interventions it has undergone.
Examining Varnish Layers: The varnish layer on the surface of paintings yellows over time and gains a fluorescent property. UVA light illuminates this aged varnish layer uniformly, allowing for a clearer view of the paint layers underneath. This can be critical in identifying an artist’s signature or a date.
Distinguishing Between Modern and Old Pigments: When the authenticity of a work of art is in question, the analysis of the pigments used is crucial. Some modern synthetic pigments fluoresce differently from the natural pigments used in olden times. An art restoration UVA lamp helps detect whether forgers have added modern paints to the work. For example, modern zinc oxide white shows a bright white fluorescence under UVA, while old lead white does not.
Analyzing Paper, Textiles, and Ceramics: UVA light is used not only on paintings but also to detect stains, repairs, or alterations on manuscripts, old parchments, fabrics, and ceramics. For instance, some types of paper will fluoresce when they have been treated with acidic inks or repairs.

Biohijyen’s UVA Lamp Features That Make a Difference in Art Restoration

The conservation and authentication of artworks are fields that require the highest level of precision and reliability. The UVA LED lamps we produce at Biohijyen Mühendislik have unique features for such sensitive tasks:

365 nm Wavelength: Provides the Most Accurate Visual Data: Our lamps emit intense light at a 365 nm wavelength, which is ideal for causing many organic and inorganic substances to fluoresce most effectively. This is the most suitable spectrum for capturing even the most subtle differences between old and modern materials.
20,000 Hours Operating Life: Reliability in Long-Term Projects: Restoration and analysis projects can last for many months. An operating life of up to 20,000 hours ensures the lamp can be used continuously and reliably for years.
Shatterproof Material: Safe and Delicate Working Environment: In an environment with valuable artworks, equipment safety must be at the highest level. The fact that our lamps are made from shatterproof material prevents potential accidents, guaranteeing the safety of both the user and the artwork.
RoHS Compliant and CE Certified: Our commitment to the environment and user health is proven by our products being free from harmful metals (RoHS) and compliant with international quality standards (CE).
