A 12-120mm zoom lens is used in photoelectric devices. It features flange connection, lightweight design, and back-focusing for distance and temperature compensation. It can identify objects up to 8 km away and is operable in temperatures ranging from -40°C to 70°C.
A 12 - 120mm continuous zoom lens is primarily utilized in handheld photoelectric telescopes or small photoelectric pods. This product employs flange connection, and its overall design emphasizes lightweight and miniaturization. The back - focusing structure form is used to compensate for the object distance and temperature. The observation vehicle can identify objects at a distance of 5 - 8 km, and the observer can recognize objects at 3 km.
It features two observation modes: visible light and optical fog reduction. The entire body structure is crafted from aluminum alloy 6 material, which can endure an impact strength of 40g/11ms. It can operate at temperatures as low as - 40°C or even - 45°C, and the high - temperature limit can reach 70°C.
