Fresnel lenses were invented over two centuries ago to help lighthouses prevent shipwrecks. They're still enhancing safety, ...
The Office of Naval Research funded the development of a simple array of six lights outfitted with Fresnel lenses mounted on the stern of a ship, called a Tactical Vectoring Equipment (TVE) display.
Micro-machining could be used to create almost flat, Fresnel lenses, that boost the electrical efficiency of solar panels, according to new research. Micro-machining could be used to create almost ...
The Harbour Town Lighthouse on Hilton Head Island is shining with a more historical glint these days after the installation of a Fresnel lens, the likes of which have guided mariners around the world ...
More than 2,000 lighthouses large and small watch over Norway’s fractal, rocky coast. Some have stood for centuries, guiding mariners through treacherous seas and safely to port. Now they all must be ...
The world of lighting hardware can be confusing waters to navigate. There are so many different options, so many different types of fixtures, quality of light and methods of creating light; how do you ...
A lens manufactured in France in 1902 is shining high atop Montauk Point Lighthouse once again. Earlier this month the U.S. Coast Guard relit the clamshell-shaped Fresnel lens, which guided mariners ...

You may know them best for their original use in lighthouses, where they're famously recognised as "the invention that saved a million ships". Or perhaps you initially think of their employment in ...
The presence of god rays (or crepuscular rays, to use a more technical and less religious term) in virtual reality is an artifact from the use of Fresnel lenses in most headsets. Unlike a traditional ...
Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered phase ...
