Athermalized 25mm F1.0 Fixed Focus LWIR Lens – Zero Refocusing Required for Extreme Temperatures (8-12μm, 640×512)
Athermalized 25mm F1.0 Fixed Focus LWIR Lens – Zero Refocusing Required for Extreme Temperatures (8-12μm, 640×512)
To achieve superior thermal stability, this lens is engineered using precision-molded Chalcogenide Glass (rather than traditional Germanium). The unique temperature coefficient of refractive index (dn/dt) of Chalcogenide glass, combined with advanced optical design, compensates for thermal defocus automatically. This guarantees that the F1.0 large aperture delivers consistently sharp, high-contrast thermal images in extreme cold or heat, from -40°C to +80°C.
Applications:
Unmanned Aerial Vehicles (UAVs), border surveillance, forest fire prevention, long-range security monitoring, and industrial automated thermography requiring ultimate stability and low maintenance.
