Thanks to our in-house developed instruments and software, we offer cultural institutions, both public and private, such as museums, libraries and archives, the opportunity to deepen their knowledge of their heritage. Using-multispectral imaging and infrared reflectography, in the case of documents it is possible to highlight erased palimpsests, analyse hidden text, improve readability and virtually erase stains. In the case of paintings, it is possible to highlight hidden details, such as the preparatory drawing, the presence of paint layers hidden by additional layers of colour given by the artist himself or due to interventions carried out subsequently, and the artist's regrets. This information is preliminary and necessary for the physical restoration phase. All this is done non-invasively and on site, without removing the artefact from its location..
