Fresnel lens arrays for passive infrared (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. We currently offer seven series of 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. The table below allows you to compare our lens array offerings to find the ideal fit for your application.
|Series||Focal Distance||Downward Tilt||Description|
|12°||Popular for burglar alarm sensors|
|XX0.9GI6TX||0.9 in (22.9mm)||6°||Popular for burglar alarm sensors; used to make smaller sensors than the XX1.2GI12VX|
|CM1.0GIVX||1.0in (25.4mm)||Ceiling mount line; used for lighting control from offices to warehouses|
|CM0.77GIVX||0.77 in (19.6mm)||Ceiling mount line; used for lighting control from offices to warehouses|
|XX0.5GIVX||0.5in (12mm)||Hemispherical, extremely rugged, board-mounted|
|XX0.25GIVX||0.25 (6.4mm)||Mounts directly to a TO-5/TO-39 package pyroelectric detector, and is available in a version that works with surface mount pyroelectric detectors from various manufacturers|
|XX.9GOVX||0.9 in (22.9mm)||Used with the grooved side of the array facing outward|

Although we offer an extensive range of standard lenses and lens arrays for PIR applications, we understand that you may need a custom designed part. Our team welcomes the opportunity to collaborate with you on custom designs. Allow us to help you achieve the custom design that works best for your application. If you purchase tooling and the resulting lens arrays from us, there is no charge for the design.
