Passive Infrared (PIR) Lens Arrays

Precision-engineered PIR lens arrays with unmatched sensitivity and accuracy.

Fresnel lens arrays for PIR applications are useful in a wide range of devices, such as automatic lighting switches, occupancy sensors, and motion sensor alarms. Fresnel lens arrays for PIR applications produce a broad, tailored field of view through the accumulation of many repeated narrow fields of view.

Standard and Custom PIR Lens Design Available

We currently offer seven series of standard, ready-to-ship PIR Fresnel lens arrays, in addition to a few assorted types. Each series contains a number of lens arrays, each of which has the same mechanical size and shape but offers a different detection pattern. 

If a custom-designed part is needed, we are happy to collaborate with you on custom PIR lens designs. If you purchase tooling and the resulting lens arrays from us, there is no charge for the design.
