Original Press Release:

LDTC Lab Series Instruments Improve Laser Diode System Performance

The LDTC LAB series instruments combine best-inclass low noise, high-end digital control laser diode driver technology with an IntelliTune® smart temperature controller. If you need stable wavelength, stable temperature, stable laser diode current or power, or low noise, these offer the best performance and value.

Two models are available, the LD2TC5 LAB and the LD5TC10 LAB. The LD2TC5 LAB outputs up to 2 and 5 A for the laser and thermoelectric, respectively. The LD5TC10 LAB outputs up to 5 and 10 A. Both models offer 10 V of laser compliance voltage and 15 V of thermoelectric compliance voltage.

The intuitive touchscreen interface and IntelliTune® PID control algorithm simplify precision operation.
