Inventor Edwin Land developed inexpensive filters to polarize light.
He founded Polaroid Corporation to commercialize the filters. Initial success came through applications for sunglasses and cameras. Other applications included 3-D glasses for movies and night-vision goggles for the military. Land also created an instant camera which developed an image in less than a minute and shared his findings at an OSA meeting. (Photo: OSA Archives)
