The 13mm F/1.0 LWIR athermal infrared lens is designed for long-wave infrared (LWIR) thermal imaging systems using 640×512 resolution detectors with 12µm or 17µm pixel pitch. Featuring a large F/1.0 aperture and an advanced athermal design, this compact lens delivers stable focus and high transmission efficiency across extreme temperature environments.
Its lightweight construction and wide field of view make it an excellent choice for UAV payloads, defense monitoring, forest fire prevention, and mobile infrared surveillance applications.
Wide-Angle Thermal Imaging – 13mm focal length provides a broad field of view, ideal for aerial monitoring and situational awareness.
F/1.0 Aperture – Maximizes energy capture, ensuring clear imaging in low-signal environments and during night-time operations.
Athermal Stability – Maintains focus across –20 °C to +60 °C without manual adjustment, suitable for harsh outdoor conditions.
Compact & Lightweight – Easy to integrate into UAV-mounted thermal cameras and handheld devices.
