75mm F/1.0 LWIR Motorized Focus Lens – High-Resolution Thermal Imaging for Extreme Environments

The 75mm F/1.0 LWIR Motorized Focus Lens is a high-end thermal imaging optic engineered for 1024×768–17μm detectors, delivering superior long-range target identification with exceptional thermal resolution and detail capture—well-suited for advanced surveillance systems, perimeter defense networks, and airborne reconnaissance platforms requiring uncompromised image quality at distance. The F/1.0 aperture maximizes infrared flux collection across the 8–12μm band, while DLC coating ensures robust protection against abrasion and corrosion. Remote focus control is enabled via a 12V DC motor drive, allowing precise adjustment without physical access—an essential feature for elevated or hazardous installation points.

Weighing ≤420g with a compact mechanical envelope, this lens integrates readily into gimbaled camera systems, fixed observation posts, and vehicle-based thermal suites. Its extended operating temperature range from –40°C to +60°C guarantees dependable functionality under severe climatic stress. This lens distinguishes itself through its balance of high-resolution detector support, ultra-fast aperture for low-signal environments, and motorized precision—delivering a powerful combination of reach, clarity, and remote operability for professional-grade thermal imaging missions where failure is not an option.
