Fresnel lenses played a crucial role in advancing lighthouse technology by significantly improving the intensity and range of light emitted from lighthouses. These lenses allowed for the effective projecting of rays from a point source, enhancing visibility for mariners. Fresnel’s innovations made it possible to create lighter and more compact lenses that could be positioned closer to the light source, thereby increasing their efficiency compared to traditional methods ([1]).
Fresnel's optical systems combined the principles of refraction and total reflection, rendering the lights brighter and more effective over greater distances. This transformation was instrumental in the shift from catoptric (reflective) to dioptric (refractive) lighthouse systems, establishing a standard for modern light signaling ([1]).
