4.240μm low power benchtop ICL-DFB tunable continuous wave laser 5mW (with TDLAS phase-locking control module)

4.240μm low power benchtop ICL-DFB tunable continuous wave laser 5mW (with TDLAS phase-locking control module)

The 4.240μm ICL-DFB laser is a tunable continuous-wave laser developed by Idealphotonics . It features a narrow linewidth, high power, and low power consumption, making it ideal for gas sensing applications, particularly for testing hydrocarbons and other related gases. The desktop ICL-DFB laser module integrates a driver and temperature control module, and also allows software-based control of the laser's temperature and operating current, ensuring stable operation and maintaining the accuracy of measurement values. Additionally, the module includes an FPGA (optional, at extra cost), facilitating the processing of gas concentration measurements.

Product features：Continuous wave、 Single-mode spectrum、 Tunable light source、 Low power consumption、 High-quality beam、 Narrow linewidth、 Software intelligent control、 Compact structure

Part Number：--

Application area：TDLAS gas system measurement setup、 Mid-infrared system light source、 Mid-infrared device analysis
