| The original light was an Argand-Lewis parabolic reflector, lit with candles and with a visibility of 2 miles. Augustin Fresnel invented a superior way of focusing light in the early 1850s and most lighthouses in the US were converted to the Fresnel Lens, with Pemaquid Point receiving a fourth order Fresnel in 1856. The lens is one of only six Fresnel lenses still in service in Maine. The keeper's house was built in 1857. |
