What is a Fresnel lens?

A Fresnel lens is an optical lens that is characterized by being thinner and lighter than traditional lenses. It typically has a disk-shaped or cylindrical structure, and is often referred to as a "stepped lens" because it is made up of many small segments, or steps. Each segment is responsible for bending light in a specific way. The main advantage of a Fresnel lens is that it is lighter and thinner than conventional lenses, making it ideal for use in large-scale lighting fixtures and concentrators. Fresnel lenses are commonly used in applications such as signal lights, projectors, and solar concentrators.

Application of Fresnel lens

✅Signal lights
Used in lighthouses and aircraft beacons to collect light and make it visible from long distances.
✅Projectors
Plays a crucial role in concentrating light for projecting images.
✅Solar concentrators
Used for collecting solar energy by focusing sunlight into heat.
✅Vehicle lighting
Used in vehicles that require high-intensity lighting.
