The ITC8102DS15 Module is a combination Laser Diode and TEC Temperature Controller for the PRO8 platform. This module offers laser drive current ranges of 0 to ±1 A and incorporates a TEC Controller that provides up to ±2 A/16 W. The ITC8102DS15 combination module comes with a 15-pin connector for laser and TEC current output. The ITC8102DS15 features exceptionally low laser current noise and exceptional temperature stability of better than 0.002 °C (AD590).

The ITC8102DS15 Module incorporates proven laser protection features to safeguard sensitive laser diodes. Besides common protection functions, such as current limits, laser current soft start, and interrupt protection, an advanced circuit design ensures that AC power-line transients or power outage, as well as RF pickup, cannot affect the laser diode. Additionally, a temperature window can be set that will shut the laser down in the event the high or low thresholds of the window are exceeded. The P- (gain), D- and I- settings of the PID control loop can each be set independently to optimize the temperature response of the system to different thermal loads.
