Mini Size Fresnel Lens S9012 Widely used in Alarm System


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.  

The advantage of the Fresnel lens is small in size, the price is very competitive. It’s popular used in the security area.

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.
