Ultraviolet, visible and infrared performance of coated glass for museums

摘要

The use of coated glasses for protecting the art works exposed to natural lighting in museums, galleries and exhibitions is investigated. A color fading has been measured on paintings as a consequence of the ultraviolet and visible radiation that falls on the object surface. The problem of damage arises also with artificial lighting, in this case the emission spectrum has a large component in the near infrared. The role of thin film coatings in preserving paintings from ultraviolet, visible and near infrared radiation damage is examined.
