    • 5.26μm Low-Power Benchtop DFB-QCL Mid-Infrared Quantum Cascade Laser, 10mW (TDLAS Integrated Control Module)

    The QCL5260-5.26um Low Power Desktop DFB-QCL Mid-Infrared Quantum Cascade Laser is a domestically leading, ultra-low power QCL-DFB laser developed by Idealphotonics in the first half of 2018. It offers a tunable range of over 100 nm and an output power greater than 40 mW, meeting industrial needs such as gas sensing for customer testing. The laser provides collimated output with stable power and superior temperature and wavelength stability, surpassing the stability of traditional high-power quantum cascade lasers by several orders of magnitude. This makes it an excellent test source for our mid-infrared testing customers.
