Product Description
Dia300mm FL(Focal Length)=24mm Optical Fresnel Lenses
Packaging& ShippingFresnel lenses are a type of compact lens originally dsigned by French physicist Augustin-Jean Fresnel for lighthouses, which 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.
