Fresnel Lens
★Exhibit Content: Fresnel lens optical principles, lens focusing/imaging characteristics, optics popular science ★Interaction: Mechanical interaction ★Operation: Visitors observe nearby objects in their hands through the Fresnel lens, and can also observe distant objects, intuitively experiencing the lens's magnification and focusing effects, and understanding the working principle of the Fresnel lens. ★Exhibit Description: The exhibit consists of a Fresnel lens assembly, a display stand, etc., and is a recommended exhibit from the KexMall exhibit store. The Fresnel lens collapses a continuous spherical surface onto a flat plane, with a cross-section composed of a series of sawtooth grooves, and the central part is an elliptical arc; each groove can be regarded as an independent small lens, concentrating light to the central focal point while eliminating some spherical aberration. This exhibit transforms classic optical principles into an interactive science exhibit, allowing visitors to intuitively understand the optical characteristics of the Fresnel lens. ★Scientific Principle: The Fresnel lens utilizes the principles of light refraction and focusing. The sawtooth grooves on its surface act as multiple independent small lenses, which can adjust light into parallel or focused beams, forming a central focal point; compared to traditional spherical lenses, it achieves the same focusing effect with a thinner thickness while eliminating some spherical aberration, making it a classic application of the principle of light refraction.
