Product Introduction
The MWIR continuous zoom thermal camera consists of a large zoom ratio continuous zoom lens and a high-sensitivity imaging detection component. The lens has a focal length range of 22mm to 700mm, and an optical zoom ratio of 30x. It employs a compact optical design and precision structural design, with special structural processing technology, high-precision optical-mechanical assembly techniques, and advanced servo control technology used during production. The imaging detection component has a resolution of 640x512@15μm and utilizes low-noise, high-sensitivity imaging technology. It features intelligent image processing algorithms such as adaptive non-uniformity correction, noise filtering, wide dynamic range image enhancement, and automatic light adjustment. It is characterized by its small size, lightweight, long focal length, long-range capability, large zoom ratio, high optical axis alignment accuracy, and clear imaging throughout the zoom range. The imaging detection component has excellent environmental adaptability, capable of providing clear and stable imaging for extended periods in extreme conditions such as high and low temperatures.
The large zoom ratio continuous zoom infrared thermal camera can be used in applications such as low-altitude reconnaissance, targeting design, coastal and border defense, key site protection, and target range testing.
