The Continuous Zoom Lens is a compact and lightweight optical solution designed primarily for handheld photoelectric telescopes and small electro-optical pods. Featuring a flange connection for seamless integration, this lens incorporates a back-focusing structure to compensate for object distance variations and temperature changes, ensuring consistent imaging performance. It offers dual observation modes—visible light and optical fog reduction—enhancing clarity across diverse environmental conditions. With a recognition range of 6–8 km for vehicles and 3–3.5 km for personnel, it delivers exceptional long-range observation capabilities. Constructed from durable aluminum alloy, the lens withstands impact forces of 40g/11ms and operates reliably in extreme temperatures from -45°C to 70°C. Ideal for electro-optical pods, surveillance and targeting systems, remote-controlled weapon stations (RCWS), and large zoom-guide lenses, this high-performance lens is engineered for demanding defense and reconnaissance applications.
