| Old Point Loma – Free Stationery, E-Card (From the Archives)
Picture an old magnifying glass. Is it round and thick, much thicker in the center?
Now make the glass bigger, big enough to focus a lighthouse's fire. Does the lens grow thicker and ever thicker in the center, heavy, unwieldy and certainly unpractical?
Augustin-Jean Fresnel saw the same problem. Focussing on what is responsible for refraction — the lens's boundary and angle, not its thickness — he did what you would do, too: he cut the glass in concentric circles into what resembles onion rings, made all the rings about the same thickness and put them back together.
A Fresnel lens's image is not a solid glass's sharp and crisp picture. The huge, lightweight and thin lenses were designed for and fit a lighthouse's needs perfectly, though. In the U.S., Fresnel lenses appeared during the 1850s replacing old reflectors and equipping shiny new lighthouses like the iconic (now Old) Point Loma:
