Product Description
55mm Lens 640x512/15µm Optical Gas Imaging Infrared Module for VOCs Gas Leak Detection
Volatile Organic Compounds (VOCs) are gases emitted into the air from industrial processes. Gas leaks pose significant safety risks to both employees and local communities.
The LFM615HZ3 is a cooled infrared thermal module specifically engineered for gas leak detection. It integrates a 640x512/15µm MCT cooled MWIR infrared detector and employs spectral wavelength filtering technology to visualize invisible VOCs that cannot be detected by the naked eye.
This thermal camera provides fast, contactless measurement capabilities for hard-to-access areas, significantly enhancing safety for both inspectors and equipment.
Main Features
  • SWaP³ Optimization: Compact size, reduced weight, and lower power consumption
  • Clear Leak Identification: 640×512 resolution with gas-enhanced HSM algorithm support
  • High Reliability & Sensitivity: Superior detection performance
  • Easy Integration: Multiple interface options with RAW/YUV image output
  • Full Scene Coverage: Suitable for handheld and long-term online monitoring applications

Frequently Asked Questions
Advantages of Optical Gas Imaging
  • Time-saving & Efficient: Large-scale real-time detection with rapid leak location, no production interruption required
  • Long Range Detection: Non-contact testing from safe distances without additional radiation sources
  • Easy Analysis: Intuitive imaging with instant storage and convenient analysis capabilities
  • Multi-function Inspection: Detection of multiple gases with excellent remote temperature measurement
Working Principle of Optical Gas Imaging
Optical gas imaging utilizes infrared technology to detect invisible industrial gases. When gases absorb infrared radiation at specific wavelengths, they create infrared radiation differences between the gas and background. The gas leak detection infrared detector with built-in narrowband filter captures infrared bands near gas absorption peaks, converting gas presence into visible infrared images through radiation differentials.
