Combination Current & Temperature Control Modules
The ITC8000 Series Modules are combination Laser Diode and TEC Temperature Controllers for the PRO8 platform. These modules offer laser drive current ranges of 0 to ±200mA, 0 to ±500 mA, and 0 to ±1 A. All three models incorporate a TEC Controller that provides up to ±2 A/16 W.

Each ITC8000 Series combination module comes in two versions, either with a 9-pin connector for laser current output and a 15-pin connector for TEC current output, ITC8000 Series or with a common 15-pin connector for both laser and TEC current output, ITC8000DS15 Series. 

Extremely Low Noise
The combination controller modules of the ITC8000 Series all feature exceptionally low laser current noise (see Specs Tab), and exceptional temperature stability of better than 0.002 °C (AD590). All of the ITC8000 Series Modules offer the same great performance independent of the mode of operation - constant current (CC), or constant power (CP).

User-Friendly Controls
The PRO8 display menu allows to configure any module in the chassis. Mneumonic symbols provide user-friendly access to all operational parameters. All settings are retained in memory and automatically recalled upon powering on the mainframe as long as modules are not being moved to a different slot.

Built-In Laser Diode Protection Features
The ITC8000 Series Modules incorporate 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, can not effect 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 ITC8000 Series Modules meet the international requirements regarding laser protection (e.g. CDRH US21 CFR 1040.10). All modules include a key-operated power switch and interlock, plus many additional features.

Calibrating the Power Display
The display of the laser power can easily be calibrated with respect to the laser's monitor diode current to provide a direct optical power read-out. This is accomplished by adjusting the “CALPD” calibration constant that is accessed via the front panel soft keys or the computer interface. Please note, an optical power meter is required for this setting procedure. See our Power Meter Family for more details.

Setting the Temperature ControlLoop
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.

Connection Cables
Depending on the ITC8000 version, different cables are required to connect the modules to a Thorlabs' Laser Diode Mount. The ITC80XX models, with 2 seperate connectors, require the CAB400 for the laser controller and the CAB420-15 cable for the temperature controller. The ITC80XXDS15 models, with one single connector, require the CAB430 cable. The cables have to be ordered separately.
