Lens Rings

starting at €90.00

Many lighthouses around the world use a lens developed by a Frenchman named Fresnel, which consists of concentric rings around a single center point and has a serrated cross-section. Because material has, in a way, been removed from it (the thick center of the convex lens and the serrated edges), the lens is thin and light for its size. The lens system of a lighthouse usually consists of several such Fresnel lens elements.

Many lighthouses around the world use a lens developed by a Frenchman named Fresnel, which consists of concentric rings around a single center point and has a serrated cross-section.

The lens system of a lighthouse usually consists of several such Fresnel lens elements.

The lighthouse stands at the edge of the world. Smoothly worn steps lead up to the lantern room. From there, you can see the shadows of the clouds reflected in the sea—and the small world of the lighthouse island. Starting in the 1950s, lighthouses began to be left without keepers or even became completely obsolete. It was not until around the turn of the millennium that the cultural and architectural value of these navigational aids, abandoned to the mercy of the weather and vandalism, began to be understood, and efforts were made to save them. Everyone who has helped save even one of our lighthouses has given a gift to all Finns.
