20200 Pir Lens

PIR Fresnel lens is widely used in body sensor switch, infrared alarm, infrared thermometers and infrared imaging. Micromu can provide users with various types angle sensor,sensing range,size, ratio test series fresnel lens.

1.Designed for passive infrared sensor applications
2.Easy to cut; high compatibility, low cost and environment
3.Optimized for dual element pyroelectric devices
4.White light immunity can reduce false triggers 
5.UV resistant for outdoor applications
6.Designed for uniform sensitivity to reduce electronic gain

Function
The Fresnel lens has two functions as follows:
1. The focusing action, soon hotly releases the infrared signal refraction (reflection) on PIR,
2. Fresnel lens divides the search coverage into detection area and non-detection area. PIR can generate pyroelectric infrared signal when moving object enters the detection area making the change of temperature.
