LWIR 9× Continuous Zoom Optic – 25-225mm F/0.92-1.5 for Long-Range Surveillance

The 25-225mm F/0.92-1.5 LWIR Continuous Zoom Lens is a high-performance 9× zoom infrared optic engineered for 640×512–17μm uncooled detectors, delivering seamless focal length transitions from wide-angle situational awareness to extreme telephoto target identification across the 8–14μm band. With a fast aperture ranging from F/0.92 at wide-angle to F/1.5 at telephoto, this lens ensures robust thermal sensitivity and image clarity across the entire zoom range, while the motorized zoom and focus mechanisms enable fully remote operation via 12V DC power supply—allowing rapid, precise field-of-view adjustments critical for dynamic surveillance, search-and-track, and reconnaissance missions where both broad scene coverage and extreme long-range detail are required.

Weighing 2.86kg (including motors), this compact yet powerful lens is purpose-built for integration into pan-tilt units, vehicle-mounted observation systems, coastal surveillance networks, and border security platforms requiring sustained long-range performance. The imaging range extends from 10 meters to infinity across the entire zoom range, accommodating both medium-range 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.
