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 |
|---|---|---|---|
| XX1.2GI12VX |
1.2" (30.5mm) |
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 | |
