Basic Specifications

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

Compatible with mainstream movements

Supports high-definition 1280×1024 detectors and is compatible with components from mainstream manufacturers.  

Image stabilization

The full-focal-length MTF (Modulation Transfer Function) approaches the diffraction limit, delivering exceptionally sharp imaging. Featuring an aspherical lens design, the lens maintains stable image quality throughout the entire zoom range without any focus shift.

DSP Controller Functions  

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

Key Features

Thermal imaging utilizes a industry-leading uncooled vanadium oxide focal-plane detector with high resolution.     640x512 , sensitive High resolution, excellent image quality

Highest-resolution performance across the entire zoom range
Compact and lightweight design
Robust and durable, ideal for harsh environmental conditions
Maintain focus across the entire zoom range, with quick zoom and focus responsiveness.
Available in multiple versions to support a variety of applications
Available with different types of front-end beam expanders (1.5x, 2x, 2.5x)

Application scenarios

Ultra-long-range monitoring: 900mm extended focal length (0.3° field of view) for border patrol, counter-UAV systems (CUAS), and maritime target tracking
Complex environment operations: Weather-resistant design meets the demands of aerospace and military applications, providing robust glare protection and performance under extreme weather conditions.
