This is an edited version of an interview that first appeared in episode 107 in February 2021. The guest is Dan Spinella, a man who is known for creating amazing replica Fresnel lenses. Dan, who is employed as an engineer at Disney World, began his Fresnel lens research and restoration work in 1992 using both acrylic and glass prisms used to restore historic lenses. Dan’s company, Artworks Florida, began creating full-scale reproduction Fresnel lenses in 2004. Some of his lenses are installed in lighthouses as aids to navigation and some are on exhibit in lighthouse museums across the country.
