A Fresnel lens is a compact type of lens originally used in lighthouses. The construction of these lenses allows for a large aperture and a short focal length without the mass that would normally be required. This large Fresnel lens is 2mm thick, 8" by 10" in size, and has 3x magnification, making it ideal for various optical experiments and educational purposes such as the study of magnification properties, light focusing and solar energy, exploring focal length, investigating lens aberrations, and demonstrating the concept of optical path length and wavefronts.
