There are two type for fresnel lens, flat and round. The main material for fresnle lens is poly methyl methacrylate. Fresnel lens ultrathin structure, large size and arbitrary shape cutting, excellent light transmittance of traditional geometric convex lens has many advantages, its weight less than convex lens and a variety of occasions. The fresnel lens is a optical element, one side is smooth, another side is by a ring a part of concentric garden composition. Fresnel lens arrays designed for Passive Infrared Sensor. The optical surface increases lens sensitivity for PIR sensor application. All the PIR sensor must work with the Fresnel Lens.
The Advantages of Products
1. Easy to install
2. High quanlity
3. Factory price
1. What is the payment term?
TT 100% in advance.
2. What is the package.
The appilcation of Fresnel Lens. When people goes in to the detect rang, Fresnel lens fouse the infrared on the PIR sensor, then the PIR sensor will change the optical signal to electrical signal in order to realize the PCB works.View More
