Photosensitivity

High light intensity, in particular through UV radiation, can cause irreparable damage to sensitive works of art, especially works made of paper, such as graphics, illuminated manuscripts or old books. Depending on time and light intensity, exposure starts biochemical processes that accelerate the organic aging process and lead to structural changes in paper, ink and paint.

Therefore, when digitizing such objects, it is imperative to pay attention to a preservation approved lighting system. With conventional methods such as line sensor technology, that requires a light intensity of up to 14,000 lux, there is a very high risk that valuable objects can be damaged. In contrast, the CMOS sensor technology we use ensures that the documents are captured fast and particularly gently. Specially developed light control modules also offer the option of adapting the lighting in accordance with preservation requirements and reducing it to a light intensity of <= 2500 lux.
