The Evolving Eye of Lighthouse Engineering
For over 60-years, the 36-inch diameter Double Drum rotating DCB-36 Aerobeacon replaced most of the Glowing Eyes of American Lighthouses. Since the mid 1940s, the large Fresnel lenses, manufactured using hundreds of handmade polished prisms, were replaced by more efficient and less costly aerobeacons.
With new advances in technology, the DCB-36 Aerobeacon is being phased out by modern acrylic optics and LED Beacons.
Bob Trapani, executive director of the American Lighthouse Foundation, explores the history of the sweeping eye of the DCB-36 Aerobeacon.
