Fresnel lenses are thin and lightweight optical components. They replace the continuous curved surfaces of traditional lenses with concentric ring-shaped toothed structures, enabling functions of beam convergence or divergence. They possess the advantages of large aperture, lightweight, and low cost, and are widely used in projection, lighting, solar energy concentration, and other fields.
Slim design: Thinner and lighter than traditional lenses.
High optical performance: capable of converging or diverging, with high transmittance.
Aberration control: The Fresnel lens has chromatic aberration and ring band scattering, and requires the use of other lenses for optimization.
