The Fresnel lens
：
The Fresnel lens (also known as the Fresnel lens, also known as the threaded lens) is a lens invented by French physicist Augustine Fresnel. Originally used in lighthouses, this design allows the construction of larger aperture lenses, which are characterized by a shorter focal length, less material, and less weight and volume than conventional lenses. Fresnel lenses were thinner than earlier lenses and therefore could transmit more light, allowing lighthouses to be seen even at considerable distances.
