MWIR zoom lens for compact UAV gimbals. The FoldIR 25–275mm f/5.5 is a lightweight MWIR continuous zoom lens, precisely crafted for integration with low-SWaP 15μm pitch VGA FPA detectors. Engineered for defense-grade ISR operations, it fits seamlessly within 5” (127mm) gimbal enclosures, enabling advanced thermal imaging on compact aerial systems.The folded optical path design drastically reduces the volume profile, measuring only 107mm x 101.5mm x 96mm including the detector, while maintaining exceptional zoom and focus performance. At just 302 grams net, the lens is optimized for payload-restricted platforms such as military UAVs and tactical drones.Capable of detection ranges exceeding 14.5km, the FoldIR 25–275mm lens delivers long-range reconnaissance capability in a uniquely portable form factor. With motorized zoom and focus, integrated RS485/RS422 control, and a ruggedized build rated to IP67 (front element), it ensures operational reliability across extreme temperature spans from -32°C to +71°C.

The Ophir FoldIR 25-275mm f/5.5 is a lightweight continuous zoom mid-wave infrared lens for 15 micron VGA focal plane array detectors, designed to fit within 5-inch gimbal enclosures on compact military UAVs and tactical drones. Its folded optical path design measures only 107 x 101.5 x 96mm including the detector interface, and weighs 302 grams, providing long-range detection capability exceeding 14.5 km in a form factor compatible with payload-restricted airborne platforms.

Motorized zoom and focus with RS-485/RS-422 digital control, IP67 front element sealing, and a rated operating range from -32°C to +71°C support reliable field deployment in demanding ISR and reconnaissance missions. The FoldIR 25-275mm is suited for integration into small stabilized gimbals where long-range MWIR imaging is needed in the most compact and lightweight package possible.
