The MIRF5.5-15.5 is a lightweight, high-performance motorized mid-wave infrared (MWIR) zoom lens designed for 3.5~5μm infrared imaging systems. With a zoom range of 18mm~280mm, a constant F/5.5 aperture, and high-transmission optics, it balances wide-angle monitoring and long-range detail capture. Its ultra-compact, lightweight design makes it ideal for UAV, vehicle-mounted, and miniaturized device applications, widely used in security, industrial inspection, and infrared reconnaissance.
