“”The Fresnel lens was, arguably, the most important development of lighthouse technology, between the erection of the Pharos of Alexandria, and the introduction of electricity in 1875. If you’ve been to the museum at Navesink Twin Lights, you’ve seen the first Fresnel lens every used in the United States.
James Risk, a doctoral candidate for his studies of the history of Fresnel lenses, will discuss the introduction of different kinds of lens technology in the United States and in other parts of the world.””
