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.
FTI ships tens of millions of PIR lens arrays per year.
Fresnel lens arrays for PIR applications produce a broad, tailored field of view through the accumulation of many repeated narrow fields of view.
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.

The template is really nice and offers quite a large set of options. It's beautiful and the coding is done quickly and seamlessly. Thank you!
It was easy to put together pages and when I was done, I could just click and have the page automatically created in HubSpot.
We built our old site using a template, and it left a lot to be desired. With SprocketRocket, we can go page by page and get the exact flow of content we need.
