The Kewaunee City Council on Monday will discuss acquiring the vintage Fresnel lens from the Pier Head Lighthouse, which has been proposed for removal.
In December the U.S. Coast Guard announced its intention to replace the Fresnel Classical lenses at the Kewaunee and Algoma lighthouses with modern light-emitting-diode lanterns, which are more dependable and energy efficient.
It was announced at that time that the lenses will be removed and preserved. “Due to the harsh environmental conditions including temperature fluctuations and ultraviolet rays, the lenses slowly deteriorate. Once removed, the lenses may be loaned to a local museum where they would be maintained in a controlled environment and placed on display.”
Developed by French physicist and engineer Augustin-Jean Fresnel in the early 1800s, the lens is divided into a series of concentric sections, which allows it to throw light in a way that is visible for many more miles than a conventional lens.
Acquisition of the lens is on the agendas of the Kewaunee Finance Committee, which meets at 6 p.m., and the full council, which meets at 7 p.m. at the Kewaunee Municipal Building, 401 Fifth St.
