Classic Fresnel lenses once exhibited in lighthouses in the 1800's are now part of our history.  Some lenses still exist in the towers, many are on display in museums.  These lenses are not only engineering marvels but also works of art.  Many approaching 150 years old, have stood the test of time, but still in need of repair, with missing or damaged prisms.

Artworks Florida manufactures reproduction prisms, available in acrylic or glass.  Acrylic prisms are cast with integral color to match the historic green hue of the classic Fresnel lens.  Glass prisms are manufactured with a similar process as the historic lenses, by slumping, grinding and polishing.
