5-150mm F/0.77-1.2 LWIR Zoom Lens for 640x512-17um and 640x512-12um Detector

The 15-150mm F/0.77-1.2 LWIR Continuous Zoom Lens is a high-performance 10× zoom infrared optic engineered for 640×512–17μm and 640×512–12μm uncooled detectors, delivering seamless focal length transitions from ultra-wide-angle situational awareness at 15mm to medium-telephoto target interrogation at 150mm across the 8–12μm band. With an industry-leading fast aperture ranging from F/0.77 at wide-angle—one of the fastest available in any LWIR zoom lens—to F/1.2 at telephoto, this lens maximizes infrared energy capture to deliver exceptional thermal sensitivity and image clarity even in the most challenging low-contrast or adverse weather conditions. The motorized zoom and focus mechanisms enable fully remote operation via 12V DC power supply, allowing rapid and precise field-of-view adjustments for dynamic surveillance, search-and-track, and reconnaissance missions where both expansive scene coverage and detailed target discrimination are essential.

Weighing ≤2.5kg, this compact yet powerful lens is purpose-built for integration into pan-tilt units, vehicle-mounted observation systems, UAV payloads, and fixed surveillance platforms requiring versatile long-range performance. The imaging range extends from 1 meter to infinity in wide FOV mode and 20 meters to infinity in narrow FOV mode, accommodating both close-range inspection and medium-to-long-distance target identification. Featuring DLC coating for superior environmental protection and reliable operation from –40°C to +60°C, this lens delivers the reach, flexibility, and durability demanded by professional-grade thermal imaging systems deployed in the most demanding operational environments.
