Optical Performance

Focal Length: The focal length range is 18 - 275mm, allowing continuous zoom to meet imaging needs at different distances and scenarios.
Aperture: The aperture is F5.5, which helps control the amount of light entering to a certain extent, ensuring image quality.
Detector Compatibility: Suitable for 640×512 cooled detectors, fully utilizing the detector's performance to obtain high-quality infrared images.
Operating Spectral Range: The operating spectral range is 3 - 5μm, belonging to the mid-wave infrared band. Image quality in this band is generally better than long-wave infrared (LWIR), offering advantages when high detection range and temperature resolution are required.
Horizontal Field of View: 30.6° at wide angle, 2.05° at narrow angle, adjustable according to focal length changes.
Optical Coating: All internal surfaces use high-efficiency anti-reflective coatings; the front surface can provide high-durability anti-reflective coatings (such as DLC) upon request.

Mechanical Characteristics

Focusing / Zoom Mechanism: Uses electric focusing and zoom mechanisms, facilitating remote control and automated operation.
Weight: Total weight is only 280 grams, featuring an ultra-compact structure suitable for devices with strict weight requirements.
Dimensions: Size is φ63.5×73mm, compact and easy to integrate into various optoelectronic platforms.  

Application Scenarios

1. Security Monitoring and Border Control (border and coastline monitoring; airport and port security; urban complex environment monitoring).
2. Industrial Equipment Status Monitoring and Fault Warning.
3. Scientific Research and Laboratory High-Precision Thermal Analysis (high-temperature process monitoring; thermal imaging basic research; new energy technology development).
4. Lightweight Applications for Drones and Mobile Platforms (power and photovoltaic inspection; disaster emergency response; agriculture and ecological monitoring).
5. Intelligent Transportation and Fire Prevention.
