Infrared Fresnel Lenses 2915

Infrared Fresnel Lenses | 360° Ceiling PIR Optics with 10mm Focus for Wide Area Thermal Detection

This Infrared Fresnel Lens (Model 2915) is designed for ceiling PIR motion sensors requiring 360° infrared detection with an 8 meter sensing radius.

Model 2915 Infrared Fresnel Lenses are engineered for ceiling-mounted PIR sensing devices requiring 360° infrared coverage. With a 10 mm focal length and an optimized optical layout, the lens distributes thermal signals across an 8 meter detection radius, enabling reliable motion recognition in indoor automation, lighting control, and security monitoring systems.

Human body infrared sensing Fresnel lenses are key components in infrared sensors, widely used in smart homes, temperature guns, security systems, infrared alarms, motion sensor switches, outdoor cameras, infrared thermometers, infrared imaging, and motion-activated lighting. Their primary function is to focus and regulate infrared radiation to ensure accurate detection.

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.
