QC750-Touch™ QC Laser Driver

       A new generation of QCL driver integrates a newly designed touchscreen UI, which greatly facilitates user operations and measurement. The circuit features extremely low current noise and temperature drift. The driver includes a TEC temperature controller and low noise current driver. It supports external analog signal modulation and displays real-time working status on the touchscreen. Our specially designed maximum current soft clamping can avoid damage to the laser chip caused by a large current. The driver also has a variety of protection mechanisms to maximize the security of the laser chip. The product is stable, reliable, and suitable for various QCL systems in university laboratories or R&D development.



  • Details
 All-in-one module includes both current driver and temperature controller;
 Linear output to TEC greatly extends the Peltier device lifetime;
 Output protection mechanisms ensure the safety of QCL chip: adjustable current clamp, output ramp start, overvoltage and undervoltage protection, overtemperature protection and short-circuit output protection;
 Touchscreen UI is convenient for user operation and status monitoring;
 It is easy to set up and fully compatible with HealthyPhoton’s QCL emitter module (HPQCL-Q).
