Applications of cylindrical Fresnel lenses
Due to its unique structure and properties, it has a wide range of applications in several fields.
1. Lighting Technology
In the field of lighting, cylindrical Fresnel lenses are often used to focus or diffuse light sources to achieve the desired lighting effect. For example, in stage lighting, automotive headlamps and solar concentrator systems, they can effectively control the distribution of light and improve the efficiency of light energy utilisation.

2.Optical Display
In optical display technology, the cylindrical Fresnel lens can adjust the propagation direction of light and improve the viewing angle dependence of the display device, thus making the screen remain clear and visible in a wider range of viewing angles. It is also used in virtual reality (VR) and augmented reality (AR) devices to enhance the user’s viewing experience.
3.Solar Thermal Collections
In solar thermal collector systems, it can be used to concentrate sunlight and increase the efficiency of heat conversion. By pointing a lens at the sun, a large area of sunlight can be focused onto a smaller receiver, which generates high temperatures that in turn drive a generator or other device.

Conclusion
Cylindrical Fresnel lenses show a wide range of applications in modern optics and optoelectronics due to their thinness and high efficiency. Whether it is in the field of lighting technology, optical display or solar thermal collector, it can provide effective solutions to meet different technological needs. With the advancement of manufacturing technology and the development of material science, the scope of future applications is expected to be further expanded, bringing more possibilities for the scientific and technological development of mankind.
