Distributed Feedback Laser (Gas Sensing)

Accuracy and real-time detection of methane gas is very important, which is used in many scenarios, including natural gas pipeline leakage monitoring, household safety and coal mining safety production monitoring.

DenseLight 1653.7 nm DFB laser is widely used in applications where accurate measurement of methane is required. By adjusting the temperature and driver current of the DFB laser device, methane concentration can be detected in real time and on line, providing the advantages of extra full concentration detection range, high accuracy and good selectivity.

Our 1653.7nm DFB laser assembly allows easy integration into commercially available methane gas sensors for our customers
