Museum conservators deploy timed lightboxes to protect fragile magic lantern slides in Sound and Vision galleries

cultural-heritage · 2026-04-21

In the Sound and Vision galleries, the Science and Media Museum has launched a new display system to conserve its recently obtained collection of magic lantern slides. These delicate slides, utilized with early projectors from the 17th century to the mid-20th century, are vulnerable to light damage. To address this, conservators designed a push-button mechanism that activates a UV-free LED lightbox for a brief 10 seconds, allowing guests to appreciate the intricate hand-painted images while reducing harm. The museum acquired these slides in September 2023, which were subsequently cleaned, assessed for condition, and digitized. Eight large slides have been framed using conservation-grade mount board and acrylic sheets, ensuring both preservation and public accessibility to these historical treasures.
