Fresnel lens

Projection display: Fresnel lenses are widely used in projection systems, and their role is to collimate and focus light. By adjusting the Fresnel lens, the brightness around the display panel can be significantly improved, and the sun spot effect can be eliminated, thereby improving the overall display brightness uniformity.

Product Description

Application areas:

Projection display: Fresnel lens is widely used in the projection system, which is to collimate and focus light. By adjusting the Fresnel lens, the brightness around the display panel can be significantly improved, eliminating the solar spot effect, thus improving the overall brightness uniformity.

Solar energy field: The Fresnel lens also has important applications in the solar energy field, such as the concentrated solar energy system (CPV) and the polythermal system (TPV). It can focus sunlight on 1 / 10 to 1 / 1,000 or smaller receiver (high-performance cells), more than 30% better than conventional flat-panel photovoltaic (FPV).

Research system: Fresnel lens is also often used in the research system, lens into 45 °± 5° Angle with the horizontal plane. If two same wavelength rays parallel through the lens, it can be focused on a 2mm diameter spot; it can also be used for visual system simulation and simulation.

Navigation lighting: The Fresnel lens is also used in the field of navigation lighting.

characteristic:

Small size, light weight, compact structure: Because the Fresnel lens is thinner, lighter, and more transparent than other lenses, it is easier to manufacture, and has a smaller volume and weight.

Good concentrating and imaging performance: The Fresnel lens has no good concentrating and imaging performance than other lenses, which makes it widely used in defense, aviation, space, industrial production and civilian use.

High cost performance: The Fresnel lens cost is relatively low, making it cost-effective in many applications.

A wide range of applications: Fresnel lenses are widely used in projection display, solar energy, scientific research systems, and navigation lighting.

Overall, the Fresnel lens is an important optical element with many advantages and applications
