Wide angle lenses like this one were used during the first live television broadcasts from space made from a black-and-white RCA television camera. The first three Apollo missions used these RCA cameras and Fairchild lenses. Apollo 10 and the lunar landing missions used color cameras.
Some astronauts objected to adding photography to their busy schedules, but their broadcasts drew millions of viewers and exposed the world to life in space, live on their home TVs. The cameras had lenses for different applications, including a telephoto lens to capture images of Earth from space.
NASA transferred this lens to the Museum in 1973.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
