Product Description
320*256 Optical Gas Imaging LWIR Cooled IR Detector for Gas Leak Detection
Product Overview
The LFD330C2 infrared detector utilizes advanced Type II Superlattice (T2SL) technology, delivering exceptional sensitivity, stability, and integration flexibility for detecting gases including sulfur hexafluoride (SF₆), ammonia, and ethylene. Its strong ability to penetrate smoke and dust allows it to work normally even in harsh environments such as chemical fumes.

LFD330C2 cooled LWIR infrared detector realizes non-contact, long-distance, real-time and high-precision detection of SF₆/NH₃ gas leakage, greatly improving the efficiency and reliability of leakage detection.

Key Features
  • Advanced Technology: Built on T2SL technology with high quantum efficiency
  • Easy Integration: Supports multiple interfaces and RAW/YUV image output
  • High Sensitivity: Superior detection capabilities for gas visualization

Frequently Asked Questions
How does an uncooled focal plane array microbolometer work?
Using the principle of infrared radiant thermal effect, uncooled infrared detectors convert infrared radiation energy into heat energy through infrared absorption material, increasing the temperature of the sensitive material. This causes specific physical parameters to change accordingly, which are then converted into electrical or visible light signals through designed conversion mechanisms to enable object detection.
What are the advantages of uncooled infrared detectors?
Uncooled infrared focal plane detectors operate at room temperature without requiring an Integrated Dewar Cooler Assembly (IDCA) device. They offer benefits including fast startup, low power consumption, compact size, light weight, long lifespan, and cost-effectiveness. While their sensitivity may not match cooled detectors, years of development have made their cost-performance ratio significantly better than cooled detectors, providing broader application prospects.
