30-180mm F/0.8-1.2 LWIR Zoom Lens – High-Speed 6× Thermal Imaging Solution

The 30-180mm F/0.8-1.2 LWIR Continuous Zoom Lens is a high-performance 6× zoom infrared optic engineered for 640×512–17μm and 640×512–12μm uncooled detectors, delivering seamless focal length transitions from wide-area situational awareness to extreme long-range target identification across the 8–12μm band. With an exceptionally fast aperture ranging from F/0.8 at wide-angle to F/1.2 at telephoto—one of the fastest zoom lenses available in its class—this lens maximizes infrared energy capture to ensure outstanding thermal sensitivity and image clarity even in low-contrast or adverse weather conditions. The motorized zoom and focus mechanisms support fully remote operation via 12V DC power supply, enabling rapid, precise field-of-view adjustments for dynamic surveillance, tracking, and reconnaissance missions.

Weighing ≤3.6kg, this rugged lens is purpose-built for integration into heavy-duty pan-tilt units, coastal surveillance networks, border security towers, and vehicle-mounted observation platforms requiring sustained long-range performance. The imaging range extends from 3 meters to infinity in wide FOV mode and 35 meters to infinity in narrow FOV mode, accommodating both close-quarters scene assessment and extreme-distance target discrimination. Featuring DLC coating for superior environmental protection and reliable operation from –40°C to +60°C, this lens delivers the reach, versatility, and durability demanded by professional-grade thermal imaging systems deployed in the most challenging operational environments.
