Fresnel Lenses

 
Fresnel Lens Arrays for PIR detectors

The Fresnel lens is a concentric stack of individual planar lenses each of which has a different refractive index. This allows construction of a lens with much less thickness than that of the standard spherical version. This is very important in infrared optics because the material from which the lens is made has significant transmission loss. The thinner the lens the lower the loss.
