Optical education: The special structure of the Fresnel lens can adjust the parallel light or the focused light, so that the light is effectively directed to a specific narrow area to achieve the focusing effect of light. The children were curious about it.This is not only a base, but also a knowledge point that children need to learn.

Tips: Wear sunglasses when using, so that the light is not too strong to damage the eyes

The working principle of Fresnel lens is mainly to use the special structure of the lens to achieve the focus of light It is flat on one side and raised on the other, so that each groove can be seen as a separate small lens, which can be adjusted to parallel light or focus light, so that the light is effectively directed to a specific narrow area to achieve the focus effect of light. Size: Φ200mm Thickness: 2mm Material: PMMA (acrylic) Groove pitch: 0.5mm Transmission (%): 92 Review: Great product!!! Review: Excellent for demonstrating how Fresnel optics work in scaled lighthouse demos. When paired with a small, bright LED, the lens produces a convincing, highly directional beam that illustrates the principle of concentrating light for visibility at a distance. For the best effect, use a pointlike light source, keep the lens flat, and shield stray light so the beam appears crisp.
