Optical Performance

Focal length: The focal length range is 18–275mm, offering continuous zoom capability to meet imaging needs for various distances and scenarios.
Aperture: The aperture is set to F5.5, which helps control the amount of light entering the lens to a certain extent, ensuring high-quality images.
Detector compatibility: Designed for 640×512 cooled detectors, this solution fully leverages detector performance to deliver high-quality infrared images.
Working spectral range: The operational spectral range spans 3–5 μm, falling within the mid-wave infrared band. Images captured in this range typically outperform those from long-wave infrared (LWIR), making them particularly advantageous when high demands are placed on detection range and temperature resolution.
Horizontal field of view: 30.6° in wide-angle mode and 2.05° in narrow-angle mode, with the field-of-view range adjustable according to changes in focal length.
Optical Coating: All internal surfaces feature a highly efficient anti-reflective coating, while the front surface can be equipped with a durable anti-reflective film (such as DLC), tailored to your specific needs.

Mechanical Properties

Focus / Zoom Mechanism: Features an electric focus and zoom system, enabling convenient remote control and automated operation.
Weight: Weighing just 280 grams in total, it features an ultra-compact design, making it ideal for installation in devices with strict weight requirements.
Dimensions: Measuring φ63.5 × 73mm, it features a compact size that makes it easy to integrate into various optoelectronic platforms.  

Application scenarios

1. Security Surveillance and Border Control (Border and Coastline Monitoring; Airport and Port Security; Urban Complex Environment Surveillance).
2. Industrial Equipment Condition Monitoring and Fault Prediction.
3. Scientific Research and Laboratory: High-Precision Thermal Analysis (High-Temperature Process Monitoring; Fundamental Research in Thermal Imaging; Development of New Energy Technologies).
4. Lightweight Applications of Drones and Mobile Platforms (Power and Photovoltaic Inspections; Disaster Emergency Response; Agriculture and Ecological Monitoring).
5. Intelligent Transportation and Fire Prevention.
