MWIR Continuous Zoom Lens 21-441mm F4.0 – New Release!
24 Aug,2025
Consistent HD Imaging, Uncompromised Quality Throughout
Utilizing advanced optical design and precise image quality optimization, this lens ensures uniform image clarity across the entire zoom range—free from fault zonesor resolution loss. From wide-angle to telephoto, every frame remains in sharp focus, delivering stable high-definition infrared video with every zoom adjustment.
Zero Narcissus Interference, True Thermal Field Reproduction
Through innovative multi-layer narcissus suppression technology and coating processes, it completely eliminates the narcissus effect common in thermal imaging systems. This prevents false signal interference, guarantees accurate temperature measurement and pristine imagery, ensuring no critical detail is missed.
Exceptional Optical Axis Consistency, Rock-Solid Stability
Featuring a reinforced mechanical structure and outstanding optical axis control performance, the lens maintains exceptional stability throughout the zoom process without any shift or jitter. This enhances system pointing accuracy and repeatability, making it ideal for high-end military, scientific research, inspection, and security surveillance applications.
Empowering Solutions Across Multiple Fields
In border surveillance, the 441mm super-telephoto capability enables kilometer-range day/night monitoring. In firefighting and rescue operations, it penetrates smoke to identify heat sources, with no need to refocus during zooming.
