Description
2327nm 5mW TO CAN Methane Detection Laser Diode
Description
This 2327nm 5mW TO-CAN laser diode is a specialized, high-stability source optimized for methane (CH₄) sensing via TDLAS. With single-frequency output, built-in thermal stabilization, and a rugged TO package, it delivers precise, long-term performance for industrial safety, environmental monitoring, coal mining, and portable gas analysis. Its narrow linewidth, low noise, and GaSb-based design ensure ultra-high sensitivity and reliability in demanding field and industrial environments.
Feature:
- 2327nm SWIR single-frequency output with 5mW CW power
- Hermetic TO-CAN package with integrated TEC, thermistor
- Low threshold current (~30mA), low drift
Application:
- Industrial Methane Leak Detection: Deployed in fixed/portable gas analyzers for oil/gas pipelines, refineries, and LNG facilities.
- Coal Mine Safety Monitoring: Integrated into underground gas detectors to continuously measure methane in mine atmospheres.
- Environmental & GHG Monitoring: Used in atmospheric stations, drone-based sensors, and landfill emission systems to quantify methane emissions.
- Industrial Process & Combustion Control: Applied in boilers, incinerators, and petrochemical processes to optimize combustion and reduce unburned CH₄.
