STJ Series TEC Drivers (Temperature Controllers)

The TEC driver is a high-performance temperature control system (air cooling) specially designed for driving laser diode (thermoelectric refrigeration chip, TEC), with high precision and high stability.It is based on the principle of Peltier effect. It has the advantages of high precision, long service life, small volume, no noise, no wear, no vibration, no pollution.
