30-150mm F/0.87-1.2 LWIR Continuous Zoom Lens – Broad-Band Long-Range Thermal Imaging Optic

The 30-150mm F/0.87-1.2 LWIR Continuous Zoom Lens is a high-performance 5× zoom infrared optic supporting 640×512–17μm and 640×512–12μm uncooled detectors, delivering seamless focal length transitions from wide-angle situational awareness to narrow-field long-range target identification across the extended 8–14μm waveband. With an ultra-fast aperture ranging from F/0.87 at wide-angle to F/1.2 at telephoto, this lens provides exceptional thermal sensitivity and image contrast, while the motorized zoom and focus mechanisms enable remote operation via 12V DC power supply—allowing rapid, precise field-of-view adjustments for dynamic target acquisition and tracking missions.

Weighing 2.98kg, this robust lens is engineered for integration into heavy-duty pan-tilt units, vehicle-mounted observation systems, coastal surveillance stations, and fixed border security towers requiring sustained long-range performance. The imaging range extends from 5 meters to infinity in wide FOV mode and 30 meters to infinity in narrow FOV mode, accommodating both close-quarters scene assessment and extreme-distance target discrimination. Featuring DLC coating for enhanced environmental durability and reliable operation from –40°C to +60°C, this lens delivers the reach, versatility, and ruggedness essential for professional-grade thermal imaging systems deployed in demanding field environments.
