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.

The LIGHTHOUSE stands at the edge of the world. The stairs smoothed by thousands of steps lead to the lantern room. From there, you can see the shadows of the clouds reflected in the mirror of the sea – and the small world of the lighthouse island or cape. In Finland lighthouses began to be left without keepers or even become completely unnecessary from the 1050s. It was not until the turn of the millennium that the cultural and architectural value of these sea markers, abandoned to the mercy of the weather and vandalism, began to be understood and efforts were initiated to save them. Everyone who has participated in saving even one of our lighthouses has given a gift to all Finns.
