VY Optoelectronics Co., Ltd. can provide various Fresnel lenses according to your requirements.Fresnel lens is a compact lens originally developed by French physicist Augustin-Jean Fresnel for the lighthouse.Fresnel lens is composed of a series of concentric rings. Compared with traditional lens, Fresnel lens reduces the amount of material required by dividing the lens into a group of concentric annular parts.It is used for light collection, light collimation, amplification etc.

What is a Fresnel lens used for?
Fresnel lens, succession of concentric rings, each consisting of an element of a simple lens, assembled in proper relationship on a flat surface to provide a short focal length. The Fresnel lens is used particularly in lighthouses and searchlights to concentrate the light into a relatively narrow beam
How are Fresnel lenses made?
The basic idea behind a Fresnel lens is simple. Imagine taking a plastic magnifying glass lens and slicing it into a hundred concentric rings (like the rings of a tree). Each ring is slightly thinner than the next and focuses the light toward the center. ... Large Fresnel lenses are often used as solar concentrators.
What can I do with a Fresnel lens?
Since plastic Fresnel lenses can be made larger than glass lenses, as well as being much cheaper and lighter, they are used in industrial applications to concentrate sunlight for heating in solar cookers, in solar forges, and in solar collectors used to heat water for domestic use.

People also ask
- Are glass lens better than plastic?
Glass is much more scratch resistant than plastic, making the glasses last longer. ... Plastic lenses are less reflective than glass lenses, making them clearer and less prone to glare. Glass lenses generally have a higher index than plastic lenses, making them slightly thinner and more attractive looking.
- Are Fresnel lenses still used?
The Fresnel lens, invented by Augustin-Jean Fresnel, helped do that by capturing all the light coming from a lamp, then magnifying and steering it in one direction. Suddenly, lighthouses became more useful and shipwrecks diminished. Fresnel lenses are still in operation today.
- Do all TVS have a Fresnel lens?
No LCD televisions have Fresnel lenses. Only projection televisions do. I removed the lens and used it for burning and melting mounted on a pivoting frame. It is brutal at full sunlight.
