10mW 1653.7nm TO-39 LD For Gas Sensing

10mW 1653.7nm TO-39 LD for Gas Sensing

Brandnew's DFB laser is built using discrete-mode (DM) technology, delivering a cost-effective laser diode with mode-hop free tuneability, excellent SMSR, and narrow linewidth. Brandnew's laser diode, available in a range from 1640 - 1670nm, is specifically designed for sensitive detection of Methane ( CH4 ). The TO-39 package is integrated with TEC and thermistor for precision temperature and wavelength control.

Feature:

• Specifically designed for Methane TDLAS detection
• DFB Laser / Single Frequency / Single Mode
• Tunable by Either Temperature or Current
• TO-39 Package with Integrated TEC and Thermistor

Application:

• Industrial Gas Detection: Suitable for online monitoring of volatile organic compounds and hydrocarbon gases in chemical plants. It supports real-time concentration analysis with high sensitivity and anti-interference performance.
• Environmental Air Quality Monitoring: Applied to atmospheric pollutant detection and urban ambient air monitoring stations. The specific wavelength ensures accurate spectral identification of target gas molecules.
• Mining & Petroleum Safety Monitoring: Used for leak detection and underground gas safety early warning in oil and gas pipelines. Compact TO-39 structure is easy to integrate into portable and fixed detection devices.
