12–60mm F/0.85–1.2 LWIR Continuous Zoom Lens – Compact Short-Range Thermal Imaging Optic

The 12–16mm F/0.85–1.2 LWIR Continuous Zoom Lens is a compact, high-speed infrared optic tailored for 640×512–12μm detectors, delivering seamless 1.33× optical zoom with a fast aperture ranging from F/0.85 at wide-angle to F/1.2 at telephoto—ideal for close-to-medium-range surveillance, perimeter security, and urban operations where rapid field-of-view adjustment is essential. With AR coating applied for enhanced transmission across the 8–12μm band, this lens ensures bright, high-contrast thermal imagery while the motorized zoom and focus mechanisms support remote operation via 12V DC power supply, enabling quick transitions between broad-area monitoring and targeted observation without mechanical refocusing.

Weighing just 710g, this lens is engineered for integration into lightweight pan-tilt units, handheld thermal cameras, vehicle-mounted systems, and UAV gimbals where size and weight are critical factors. The imaging range extends from 10 meters to infinity in narrow FOV mode and 1 meter to infinity in wide FOV mode, accommodating both close-up inspection and medium-range reconnaissance. Designed to operate reliably from –40°C to +60°C, this rugged zoom lens delivers the flexibility, responsiveness, and optical performance required for professional-grade thermal imaging applications in dynamic and demanding environments.
