History of Radioptican Projector

The Radioptican was a popular form of home entertainment in the early 1900s, serving as an opaque projector that displayed non-transparent images, such as postcards or prints, onto a wall or screen. Produced by companies like H.C. White and Keystone, these simple devices operated by reflecting light off the object rather than passing light through a slide, offering a novel way for families to share images before modern electronic media.
