How Round PIR Fresnel Lenses Work
The round PIR Fresnel Lens divides infrared radiation into multiple zones and focuses it onto a pyroelectric sensor. When a human or object moves across these zones, changes in infrared energy are detected, triggering motion-activated systems. The lens design ensures wide-angle detection while keeping the optical path stable.
Customized Services Yuying offers customized Fresnel lenses based on customer requirements, including different sensing angles, detection distances, sizes, and test ratios. All of our products are made using original molds, preserving the accuracy of the original design and reducing the precision loss and time delays caused by secondary mold changes. New products are typically available for sample delivery within 30 days. | ![]() |
