One of The Twin Lights Fresnel Lenses
Twin Lights holds a prominent place in American maritime history as the site of the first use of the Fresnel Lens. In 1841, two of these revolutionary lighthouse lenses were installed: a “first-order” light in the South Tower and a “second-order” light in the North Tower. Developed by French physicist Augustine Fresnel, they were far superior to any navigational lighting apparatus being used in the United States at that time.
