Digital Laser Driver Board | Fully Compatible 0~1000mA Drive for VCSEL/DBR/DFB/ICL/QCL | ±0.001℃ Precision Temperature Control [DLC Series]
DLC series laser driver boards are designed for semiconductor lasers below 1000mA, including VCSEL, DBR, DFB, LD, ICL and QCL devices. They support continuous current adjustment from 0~1000mA, with output current controlled linearly by the input voltage, and integrate an ultrahigh-precision TEC temperature controller with ±0.001℃ accuracy. They are suited to demanding industrial sensing, medical equipment and fiber-optic communications applications, supporting efficient, stable laser-system operation. The DLC digital laser driver board drives all lasers within 1000mA, including VCSEL/DBR/DFB/LD/ICL/QCL lasers.
