Third order Fresnel lens in new Point Loma Lighthouse near San Diego, California
The steamer Corona arrived in San Diego on February 3, 1891 with the new lens, described by the local paper as “a $4,000 affair from France.” The lens may have originally been intended for the Anclote Key Lighthouse in Florida, as the plate on the pedestal in the New Point Loma Lighthouse bears the following inscription: “ANCLOTE KEYS FLORIDA Henry Le Paute Engineer PARIS 1887.” After it was assembled in the lantern room, the lens was illuminated for the first time on March 23, 1891. The community helped celebrate the inaugural lighting with a sailing party to the point and a moonlight picnic. The third-order lens has twelve bull’s-eyes, and a red pane of glass was placed in front of every other one to produce the desired characteristic. After winning another prize in Chicago, the lens originally manufactured for the New Point Loma Lighthouse was placed in the Chicago Harbor Lighthouse, where it was used until the early 1960s.
