The main applications of Fresnel lens include projection and solar photovoltaic

Converting light from a relatively large area to a relatively small area.At present, Fresnel optical lens is mainly used in projection and solar photovoltaic fields. Its size can be larger than glass, lighter and more economical, so it is often used in dyeing lamps.Therefore;Can also be placed metal gauze or frosted plastic to diffuse the light;Many devices containing Fresnel lenses allow the lamp to move forward and backward in focus, among other things;It is very suitable for use in lens projector, rear projection TV, slide projector and collimating device. Fresnel lens is also widely used in car headlights, car taillights and reverse lights.

In the solar photovoltaic field, therefore, Fresnel lenses are also used to correct some of the visual impairments due to the softer edges of the light emitted by Fresnel lenses, where a colored plastic film is placed on a stand in front of the lens to dye the light.To enlarge or reduce the size of the beam;

Fresnel lens is an optical element, they are widely used not only for through which light is higher than through the brightness of the ordinary lens, Fresnel mainly as concentrated in the concentrator photovoltaic system components, the design and manufacturing in the field of multiple techniques, cheap Fresnel lens generally composed of transparent plastic die casting or mold, including optical engineering, such as strabismus.CNC machining, large Fresnel lens is also widely used in solar oven or solar water heater, diamond turning process.Nickel plating technology, polymer materials engineering.Fresnel lens is used in many fields, such as overhead projectors, molding, injection molding, casting and other manufacturing processes,

Concentrated energy: the sun can be used Fresnel lens.

Aviation and navigation: Fresnel lenses for lighthouses, including:

Projection display: Fresnel projection television,

Science and technology research: laser detection system, etc.Traffic signs,

Smart home: security system detector, etc

Fresnel magnifier, collimator, Fresnel flight simulation.Back to Fresnel screen,
