Fresnel Lens
written by Carl Rod Nave
This webpage, from HyperPhysics at Georgia State University, contains an introduction to the Fresnel lens, a design that vastly reduces the amount of glass required for large lenses.  The lens is described and diagrams are provided to illustrate how these lenses work.  Links to more information are also provided for key terms and other related light and vision topics.
