1.PIR sensor must work with the Fresnel lens, to insure the long detect rang. Fresnel lens is the precision optical lens. Combining the products case, we can design different shape for fresnel lens. Fresnel lens arrays designed for Passive Infrared Sensor. 

2.The optical surface increases lens sensitivity for PIR sensor application. All the PIR sensor must work with the Fresnel Lens. Fresnel Lens can be made of polyolefin, glasses. One side is smooth, another side with thread.
