It can be 12 feet in height and more than 6 feet in diameter. Used primarily as a seacoast light, its beam is visible over twenty miles out to sea. Fresnel Lenses are optical lenses consisting of a series of concentric grooves etched into a plastic substrate. Each groove acts as an individual refracting surface, while the thin substrate minimizes the amount of light lost due to absorption.

The Fresnel lens is differentiated from traditional LED lamp, in terms of the design of focal length and distance, which establishes the effective emergent light angle. 3. Compared to traditional products, the super thin structure of Fresnel lens enables improved light transmissibility.

Fresnel lens definition is - a lens that has a surface consisting of a concentric series of simple lens sections so that a thin lens with a short focal length and large diameter is possible and that is used especially for spotlights. Collimated light is incident from the lens plane side and is converged to the focal point on the Fresnel side.
