UV fluorescence enables to evaluate the state of conservation of a work of art and to locate restored areas, even when they appear indistinguishable to the naked eye.

The system developed by GBC is based on multispectral acquisition (7 bands, width 40nm FWHM, spectral range 400-700 nm) of the fluorescence image of the artwork by a high resolution cooled CCD camera.

The UV source is a Xenon flash lamp synchronized to the camera shutter. Digital multispectral acquisition enables;
-the spectral and colorimetric characterization of materials,
-the observation of fluorescence in single spectral bands
-multivariated data processing and analysis, this represents a significant improvement with respect to traditional photographic techniques.
