The L8009 Fresnel Lens from SENBA is a high-performance optical component designed for advanced passive infrared (PIR) motion detection systems. Manufactured from durable HDPE material, it ensures excellent infrared transmission efficiency, strong mechanical stability, and long-term reliability for smart sensing and automation applications.
This Fresnel lens is engineered to enhance PIR sensor coverage by precisely focusing infrared energy into multi-zone detection patterns. It features an ultra-wide 140° detection angle combined with an effective sensing distance of up to 10 meters, making it ideal for wide-area motion detection applications. The optimized optical design reduces blind spots and improves detection sensitivity, stability, and accuracy.
With an 11.5mm compact form factor, the L8009 lens is suitable for integration into modern PIR modules and smart devices where both wide coverage and space efficiency are required. The HDPE material provides excellent resistance to environmental stress while maintaining consistent optical performance over time.
Compared to standard 120° Fresnel lenses, the L8009 offers expanded field-of-view coverage, improved detection uniformity, and enhanced infrared focusing performance for more reliable motion sensing.
