Large Fresnel Lens
A Fresnel lens is a type of composite compact lens originally developed by French physicist Augustin-Jean Fresnel (1788–1827) for lighthouses. It has been called "the invention that saved a million ships.
The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. A Fresnel lens can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances.
Wuhan Especial Optic offers OEM service. And we can custom the lens strictly per your requirements based on your project. There are many sizes of Fresnel lenses in stock, so please tell us the specs you need, we will find a cheap lens for you.
