6mm F/1.2 LWIR Ultra-Wide-Angle Fixed-Focus Lens for 1280x1024-12um Detector

This 6mm F/1.2 LWIR wide-angle lens is a high-performance infrared optic tailored for 1280×1024–12μm high-resolution detectors, delivering an extraordinary 155°×122° field of view that captures vast scenes in a single frame—ideal for large-area surveillance, UAV aerial reconnaissance, and panoramic situational awareness systems. With an F/1.2 aperture and >88% average transmission across the 8–12μm band, the lens ensures excellent thermal sensitivity and image brightness even in low-contrast environments, while its fixed-focus design offers hassle-free operation from short to medium distances.

Housed in a robust 80mm×80mm×49.3mm body weighing 236g, this lens features an M34×0.5-6g thread mount for secure system integration and precise back focal distances (17.7mm BFD, 9.7mm BWD, 13.25mm BFL) to facilitate straightforward optical alignment. Engineered to operate reliably from –40°C to +80°C, it is built to withstand harsh field conditions. Optional AR coatings are available to further enhance transmission and suppress stray light, making this lens a versatile and dependable solution for high-end thermal imaging platforms requiring maximum spatial coverage without compromising image quality.
