All WH-Clear infrared lenses are available for volume delivery, and the 25–150mm F1.4 HD uncooled long-wave infrared continuous zoom lens is one of its flagship models.

Real-World Verification of Long-Range Imaging

    In real-world shooting, lettering on a rooftop about 800+ meters away is clearly legible, with stable contours and no obvious blur or ghosting; high-rise urban buildings roughly 7 km to the rear side are captured in the same frame, with clear imaging and distinct layering. With the naked eye in the same scenario, only the rough outlines of the buildings can be discerned, whereas this lens faithfully records details of distant targets—its imaging performance stands up to real-world testing.

Wide-Angle and Telephoto Each Fulfilling Its Role

    At the 25mm wide-angle end, a 34.15°×27.61° wide field of view covers an entire building and its surrounding area; a single installation enables full fa?ade thermal imaging scanning, with natural edge transitions, laying a solid panoramic foundation for zooming in. Pushed to the 150mm telephoto end, the 5.86°×4.69° narrow field of view focuses on the rooftop, with no stuttering, frame skipping, ghosting, or optical axis shift throughout—focus stays locked and the image remains smooth and coherent.

Stable Imaging in Low Light and Thin Fog

    The F1.4 large aperture, combined with the 8μm–12μm long-wave infrared band, enables the lens to capture temperature signals under conditions of dark night with no light, thin fog and airborne dust, and backlight or strong light. In actual footage, building temperature differences are clearly layered, temperature distribution of distant targets is discernible, and high signal-to-noise ratio imaging keeps the picture clean and crisp. For nighttime dynamic capture, when flocks of birds sweep across the city sky, their flight postures are clear and transparent with no ghosting; the contours and movements of pedestrians tens of meters away, as well as the layering of tree branches and leaves, are distinct—balancing both long-range search and close-range inspection.

Lightweight and Compact, Adaptable to Multiple Carriers

    The unit weighs ≤1.8kg with dimensions of Φ130mm×141mm, and can be mounted on gimbals for fixed duty, pods for aerial photography, handheld inspection, and other carriers. Full-range focusing from 5m to infinity enables rapid focus lock on near and far targets; the front surface features an AR anti-reflection coating, with optional DLC hard protective coating, offering dust, moisture, wear, and corrosion resistance—adapting to outdoor wind, frost, rain, and snow, and meeting the long-term outdoor operation needs of building security, fire inspection, and building energy-efficiency testing.

Volume Delivery, Multi-Scenario Supply

    The 25–150mm F1.4 HD is supplied for scenarios including urban nighttime traffic flow and bird monitoring, park security, road traffic monitoring, suburban full-area patrol, and field situational monitoring. It adapts all-weather to complex environmental monitoring needs and is delivered in batches according to project plans, ensuring project progress across scenarios.
