Overview

A Fresnel lens is an important optical element.

Applications

Projection display: Fresnel lenses are widely used in projection systems, where their function is to collimate and focus light. By adjusting the Fresnel lens, the brightness around the display panel can be significantly improved, eliminating the sunspot effect, thereby improving the overall display brightness uniformity.; Solar energy field: Fresnel lenses also have important applications in the solar energy field, such as in concentrated photovoltaics (CPV) and thermophotovoltaic (TPV) systems. They can focus sunlight onto a receiving surface (high-performance solar cell) 1/10 to 1/1000 or even smaller than the incident surface, increasing power generation efficiency by more than 30% compared with traditional flat-panel photovoltaics (FPV).; Scientific research systems: Fresnel lenses are also often used in scientific research systems, with the lens forming an angle of 45°±5° with the horizontal plane. If two light rays of the same wavelength pass through the lens in parallel, they can be focused onto a spot with a diameter of 2mm; it can also be used for visual system simulation and emulation.; Marine lighting: Fresnel lenses also have applications in the field of marine lighting.

Key Features

Small size, light weight, and compact structure: Because Fresnel lenses are thinner, lighter, and more transparent than other lenses, they are easier to manufacture and have smaller volume and weight.; Good light concentration and imaging performance: Fresnel lenses have good light concentration and imaging performance that is not inferior to other lenses, which gives them wide applications in various fields such as national defense, aviation, space, industrial production, and civilian use.; High cost-effectiveness: The cost of Fresnel lenses is relatively low, giving them high cost-effectiveness in many applications.; Wide range of application fields: Fresnel lenses are widely used in fields such as projection display, solar energy, scientific research systems, and marine lighting.
