Product Description

General Introduction: The fresnel lens is mostly made of thin sheets of polyolefin materials, but also made of glass. One side of the lens surface is smooth, and the other side is engraved with concentric circles from small to large. Its texture is designed according to the requirements of light interference and relative sensitivity and receiving Angle.
Fresnel lens in many cases equivalent to infrared and visible light convex lens, the effect is better, but the cost is much lower than ordinary convex lens. It is mainly used in places where the accuracy is not very high, such as slide projector, film magnifying glass, infrared detector, etc.

Main function:
1. Focusing effect, that is, thermoluminescence infrared signal refracts (reflects) on PIR
2. The detection area is divided into a number of bright areas and dark areas, so that moving objects entering the detection area can generate variable thermoluminescence infrared signals on THE PIR in the form of temperature changes.
