The lens first devised by Augustin Fresnel (pronounced fraynel) (1788-1827) is a beehive shape of concentric annular sections that cast parallel beams of light. Comprised of 282 individual prisms, the first order lens can cast a beam of light that can be seen from more than 20 miles. Seguin’s lens was crafted by Augustin Henry-Lapaute of Paris and installed in 1857. The original lamp was lit by kerosene and burned about 2 gallons per hour. In 1907 it was changed to vaporize the oil and the wicks were replaced by a mantle. In the 1950’s electricity came to the island and the lamp was replaced by a thousand watt high powered electric bulb, which is still in use today.

In 1853, is was recommended by the Lighthouse Board that the new tower should be a First Order Station because of the importance of shipping on the Kennebec and Sheepscott Rivers. When the new/current tower was erected, the rare First Order Lens was installed.
