A film strip viewer, also known as a filmstrip projector, is a device used to view photographic film strips. Film strips are a type of photographic film that contains a series of images arranged in sequence. The film strip viewer allows the user to view these images in a controlled manner, typically by projecting them onto a screen or wall. Film strip viewers were commonly used in educational settings, such as schools and libraries, during the mid-20th century. They were often used to teach subjects such as history, science, and social studies. The film strips would be accompanied by an audio recording that provided additional information and context for the images. The design of film strip viewers varied, but most consisted of a light source, a lens, and a film transport mechanism. The film strip would be loaded into the viewer and threaded through the transport mechanism. The user would then turn a crank or press a button to advance the film strip, causing the images to be projected onto a screen. While film strip viewers have largely been replaced by digital media in modern educational settings, they remain an important part of the history of educational technology. They are also still used by some hobbyists and collectors who appreciate the unique aesthetic and nostalgia associated with this type of technology.
