The Chance Connection: Development of the Dioptric Lighthouse Lens - Part 1

Readers of The Keeper's Log have had occasional glimpses into the Chance lighthouse heritage, thanks to the painstaking research of Thomas Tag and other members of the Lens Committee. A Chance lens sits atop one of America's best known lighthouses, Heceta Head in Oregon, and recently the Ponce Inlet lighthouse museum in Florida has restored a 4th order Chance lens sourced from Australia, now on display among many other beautiful examples of maritime design engineering.
