Infrared Fresnel lens is primarily used to transmit infrared light for motion detector use. Passive Infrared PIR Fresnel lenses are molded in a flexible, 0.457mm thick, High Density PE.
Advantages of this product are: least absorption loss in the 8-14 micron region, extremely thin with consistent thickness across the lens, large apertures and minimal thermal expansion. The design of an infrared-transmitting Fresnel lens involves many complex considerations. Unlike other custom design of our products, we can not afford design service for PIR Fresnel items.
Focal length: 5mm
Detectable distance: 5m
Viewing angle: 120°
