15-150mm F/0.77-1.2 LWIR Uncooled Continuous Zoom Lens for 640x512-17um Detector

The 15-150mm F/0.77-1.2 LWIR Continuous Zoom Lens is a high-performance 10× zoom optic purpose-built for 640×512–17μm uncooled detectors, delivering seamless focal length transitions from ultra-wide-angle scene capture at 15mm to medium-telephoto target discrimination at 150mm across the 8–12μm band. With an exceptionally fast aperture ranging from F/0.77 at wide-angle—among the brightest in any LWIR zoom lens—to F/1.2 at telephoto, this lens maximizes infrared flux collection to ensure outstanding thermal sensitivity and high-contrast imagery even in low-contrast or adverse atmospheric conditions. The motorized zoom and focus mechanisms support fully remote operation via 12V DC power supply, enabling rapid, precise field-of-view adjustments essential for dynamic surveillance, search-and-track, and rapid deployment scenarios where both broad situational awareness and detailed target interrogation are required. 

Weighing ≤2.6kg, this rugged yet compact lens is designed for integration into pan-tilt units, vehicle-mounted observation systems, UAV gimbals, and fixed security posts 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 close-range inspection as well as medium-to-long-distance target identification. Featuring DLC coating for superior environmental resilience 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.
