It widely used in smart home products, security system, alarm system, human switch, etc. Senba is the professional manufacturer for fresnel lens more than 15 years. We can design different angle, size, detect distance fresnle lens to satisified customer requirement.
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.
