Based on Fresnel lens theory, our company designs and manufacture high clear reading magnifier. It is wildly used in teaching demonstration, reading, looking at map,watching mushroom cultivation and others. By material, there are PVC materials and PMMA material. By shape and appearance, there are bu

1、 PrincipleFresnel lens is a special type of lens that reduces the thickness of the lens by continuously cutting circular grooves on the surface of the lens, thereby achieving the functions of refraction and focusing. It can concentrate light into a relatively small area, increasing the intensity o

Fresnel lens is used to LED light source to increase the effect of light and improve the brightness of the effect.Compared with the same lens and LED lamp, the focal distance is different, the distance is different, it can set the light angle, single or multiple array LED lights. The lens can be des

Reflective wide-angle Fresnel lens is widely used in the bank ATM (automatic teller machine),security area and other areas.The characteristics of the lens are light weight, small volume, wide visual range, good anti-impact performance. CharacteristicsThe shape of a flat mirror but with the convex mi

The light emitted by LEDs is relatively concentrated within a small range of solid angles, and reflectors are no longer necessary optical components. Instead, Fresnel lenses are often used as quasi optical components to improve the beam through secondary optical design and achieve the desired effect
