Infrared Radiation - Infrared radiation (IR) exists in the electromagnetic spectrum at a wavelength that is longer than visible light.Infrared light is used in industrial, scientific, and medical applications. Night-vision devices using infrared illumination allow people or animals to be observed without the observer being detected. In astronomy, imaging at infrared wavelengths allows observation of objects obscured by interstellar dust. Infrared imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.
.
Infrared Motion sensor with the Fresnel lens work in the industry, household, medical treatment etc. The motion detecting sensor fresnel lens picturers as below.
We offers a complete range of PIR motion detecting fresnel lenses
sizes and types for the infrared application. We could custom the PIR detecting fresnel lens according
to client requirement. Inquiries are welcome at our offices.
