The Fresnel lens function has two:

        One, the focusing action, soon hotly releases the infrared signal refraction (reflection) on PIR

       the second function is divides into the search coverage in certain area pellucidae and the dark area, causes to enter the search coverage the motion object to be able to produce by the temperature change form on PIR changes releases the infrared signal hotly.

Our fresnel lens are divide to 5 series base on their shape and size, below Dia.30mm round shape series ( total 29 types), above Dia 30mm round shape series ( total 15 types), Square shape series (total 44 types), flat round shape series (total 8 types), and special shape lens series ( total 8 types).
