20-60mm Continuous Zoom LWIR Lenses

PRODUCT OVERVIEW

Our Long-Wave Infrared (LWIR) lenses are specialized thermal optical assemblies engineered to collect thermal radiation emitted by room-temperature objects. These optics precisely focus IR energy onto high-sensitivity uncooled microbolometer Focal Plane Array (FPA) detectors, specifically those utilizing Vanadium Oxide (VOx) technology.

Since standard optical glass is completely opaque to the 8–14 μm spectrum, we utilize premium IR-transparent crystals and chalcogenide glass to ensure maximum transmission and superior image clarity.

Core Advantages of the 8–14 μm Band:

Peak Thermal Detection: This waveband is optimized for objects between -40°C and 300°C, where thermal emission naturally peaks12.

Unmatched Environmental Performance: Operating without the need for external illumination, our LWIR optics function flawlessly in total darkness and through atmospheric obscurants such as fog, smoke, and haze4more_horiz.

The Industry Standard: The 8–14 μm range remains the mainstream choice for high-reliability civilian and industrial thermal imaging applications315.

KEY FEATURES

13x Continuous Optical Zoom: High-versatility imaging for long-range precision.

Advanced AS+DOE Design: Ensures superior image clarity and maximum transmission.

Rock-Solid Stability: 3-CAM zoom structure maintains boresight precision within 3 pixels.

Industrial-Grade Durability: High-precision brushless drive with a 10-million-cycle lifespan.

Ruggedized for Outdoors: Sealed, waterproof front element for the harshest environments.

HD Optimized: Fully supports 1280-resolution detectors with zero vignetting.
