The infrared thermal imaging lens of a drone is a critical optical component in the drone's infrared thermal imaging system. Its primary function is to collect, focus, and transmit infrared radiation emitted by target objects, allowing the infrared detector to convert it into visual thermal images. These lenses are typically made from special optical materials (such as germanium, zinc selenide, chalcogenide glass, etc.) that exhibit high transmittance in the infrared spectrum, effectively reducing infrared radiation loss and ensuring the detector receives signals of sufficient intensity. The design of drone infrared thermal imaging lenses emphasizes lightweight, miniaturization, and high optical performance to accommodate the payload and space constraints of drones. Many modern lenses also feature continuous zoom functionality, enabling drones to flexibly adjust the field of view during flight—for both wide-area searches and precise observation of distant or detailed targets. Additionally, to adapt to complex environmental
