Multispectral Digitization
Making the Invisible Visible
In scientific digitization projects, capturing only the visible spectrum is often not enough. The goal is to minimize stress on the original while gaining comprehensive insights into its material composition, creation process, and alterations over time.
Standard imaging techniques use only the visible range of the electromagnetic spectrum (approx. 400–700 nm). To reveal hidden details such as underdrawings, overpainting, material damage, or retouching, ultraviolet (UVA, UVB, UVC) and infrared (IR) radiation are additionally employed:
- UV imaging visualizes aging processes, past restorations, and organic materials through fluorescence phenomena. We can produce UV fluorescence images in three ranges (254–365 nm).
- Infrared imaging penetrates upper paint layers, revealing sketches, corrections, and compositional changes invisible to the naked eye (approx. 1000 nm).
For immovable or large-scale works such as murals, large canvases, or historical decorations, controlled lighting is essential.
To meet this need, we developed the CUBE (Culture Heritage Unit Box for Enhanced Scanning) — a mobile, light-tight imaging system that allows multispectral digitization of large objects on-site, whether upright or flat, independent of ambient light.
Typical applications:
- Paintings
- Murals
- Minerals
- Manuscripts and documents
- Material analysis
