Fresnel lens (Fresnel lens), also known as threaded lens, is mostly a thin sheet made of polyolefin material, and also made of glass. The surface of the lens is smooth on one side, and the other side is engraved with concentric circles from small to large. , its texture is designed according to the requirements of relative sensitivity and receiving angle by utilizing the interference of light and interference, and the requirements of the lens are very high. A high-quality lens must have a smooth surface, clear texture, and its thickness varies with the application, mostly around 1mm. The characteristics are large area, thin thickness and long detection distance. The Fresnel lens is equivalent to a convex lens of infrared and visible light in many cases, and the effect is better, but the cost is much lower than that of the ordinary convex lens. It is mostly used in occasions that do not require high precision, such as slide projectors, film magnifiers, infrared detectors, etc.

 

Application field
 

Solar Energy: As solar concentrators, Fresnel lenses focus sunlight onto small, high-efficiency solar cells, enhancing power generation efficiency and reducing the cost of photovoltaic systems.
 

Lighting Equipment: In LED lamps, Fresnel lenses collimate and diffuse light to achieve uniform illumination. They are widely used in automotive headlights, stage lighting, flashlights, etc.
 

Optical Instruments: Used in magnifying glasses, projection devices, and auxiliary lenses for microscopes to achieve magnification and imaging functions at a lower cost.
 

Security and Sensing: In passive infrared (PIR) detectors, Fresnel lenses focus the infrared radiation emitted by humans onto sensors, expanding the detection range and enhancing sensitivity.
 

Projection Display: In projectors and head-up display (HUD) systems, Fresnel lenses help adjust the optical path to achieve large-sized, clear image projection.
 

Aerospace and Maritime: Used to manufacture lighthouse lenses, enhancing the range and visibility of lights; applied in aircraft cockpit display systems for light guidance and focusing.
