The Absecon Lighthouse was designed by George Meade and still retains its original first-order fixed Fresnel lens. The lens is made of lead glass and weighs 12,800 pounds (5,800 kg) [ 4 ] As the light was fixed (non-flashing), it does not have a landward segment allowing visitors to look up in the lens where the keepers entered it for maintenance.

In June 2011, the General Services Administration made the Miah Maull Shoal Light (along with 11 others) available at no cost to public organizations willing to preserve them.
Augustin-Jean Fresnel [Note 1] (10 May 1788 – 14 July 1827) was a French civil engineer and physicist whose research in optics led to the almost unanimous acceptance of the wave theory of light, excluding any remnant of Newton's corpuscular theory, from the late 1830s [3] until the end of the 19th century.
