HDPE Human Body Infrared Lens

HDPE Human Body Infrared Lens with Quad-Element Optical Design for High-Bay PIR Detection Systems

The Quad-Element HDPE Human Body Infrared Lens is engineered for high-ceiling PIR sensing systems that require extended coverage and reliable infrared signal concentration.

With a 30mm focal length, 360° optical pattern, and an impressive 19-meter detection radius, this lens is optimized for ceiling installations up to 8 meters, enabling efficient monitoring of expansive indoor environments.

Its quad-element optical architecture enhances infrared signal distribution and supports stable performance in demanding applications such as warehouses, logistics centers, transportation facilities and high-bay commercial buildings.

What is the Quad-Element HDPE Human Body Infrared Lens?
The Quad-Element HDPE Human Body Infrared Lens is a large-format Fresnel lens designed for ceiling-mounted PIR sensors installed at heights up to 8 meters. With a 30mm focal length, 360° optical coverage and a 19-meter detection radius, it is engineered for reliable infrared sensing in expansive indoor environments where conventional ceiling-mounted lenses may not provide sufficient coverage.
