HDPE Plastic Fresnel Lens Dome Clear
S9001 Fresnel Lens is widely used in human motion switch, intrusion alarm systems, and infrared thermal sensors. There are different angles, detect distance, sizes of this available in the market. The Fresnel lens is an 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 the PIR sensor application. All the PIR sensors must work with the Fresnel Lens. The Fresnel lens is more competitive than the traditional optical lens.
