Three Lenses at Manitowoc

Thanks to George McCourt for contributing this photo of the Fresnel lens collection of the Wisconsin Maritime Museum in Manitowoc. From left to right, we see:

  1. the fourth-order lens of the Manistique East Breakwater Light, Michigan;
  2. the fourth-order lens of the Manitowoc Breakwater Light; and
  3. another fourth-order lens from the Milwaukee Breakwater Light. This lens had also been used earlier (1906-1926) on the Milwaukee Pierhead Light.
