==Behind the scenes==
A Fresnel lens is a type of lens that is divided into a set of concentric annular sections, originally developed by French physicist Augustin-Jean Fresnel for use in lighthouses.
Fresnel lenses were mentioned in a segment titled "Affirmation for Amber Day Six: My Love Flows Ambiently and Infinitely," written by Bob Carrau for the 1993 book Monsters and Aliens from George Lucas, a publication that collects concept designs and photographs from various George Lucas projects. Lucasfilm employee Leland Chee, who maintains the Holocron continuity database, has indicated that information contained in the book is non-canonical.
