Basic Specifications

Focal length range 15-330mm, constant F/4.0 aperture, compatible with cooled MWIR detectors with 640×512 resolution and 15μm pixel size (operating wavelength 3.7-4.8μm).  

Compatible with Mainstream Modules

Supports HD 1280×1024 detectors, compatible with mainstream manufacturer devices.  

Imaging Stability

Full focal length MTF (Modulation Transfer Function) close to diffraction limit, ensuring high-definition imaging. Uses aspherical lens design, no focus shift during full zoom, stable image quality.

DSP Controller Functions  

Real-time processing of imaging signals, supports dynamic aberration correction (such as electronic de-rotation), suitable for airborne and other moving platforms, collaborates with FPGA to implement dispersion compensation, carrier phase recovery, and other algorithms to improve image stability.  

Features

Thermal imaging uses industry-leading uncooled vanadium oxide focal plane detectors, resolution     640x512 , high sensitivity, good image quality

Highest resolution performance across the full zoom range
Compact and lightweight design
Durable and rugged, suitable for harsh environmental conditions
Maintains focus throughout the zoom range, with quick zoom and focus response
Offers multiple versions to support various applications
Can be equipped with different types of front beam expanders (1.5x, 2x, 2.5x)

Application Scenarios

Ultra-long distance monitoring: 900mm extended focal length (field of view 0.3°) for border patrol, counter-UAS (CUAS), and maritime target tracking.
Complex environment operations: Weather-resistant design meets aviation and military requirements, supports strong light protection and extreme weather conditions.
