Introduction
The TED8000 Series Modules are plug-in temperature controllers for our PRO8 Platform. They provide excellent temperature stabilization, typically ±0.001 °C (AD590 sensor), for optimal laser operation and other applications requiring precise thermal control. This facilitates highly stable operation of temperature sensitive components, for example optical nonlinear birefringent crystal, where phase matching requires sensitive control of the crystal’s temperature. Separate adjustment of the P, I and D settings of the temperature control loop enables optimal settling times for different thermal loads. The TED8000 Series of temperature controllers are ideal companions to our LDC8000 Laser Diode Current Controller Modules. When the TED8000 module is used with a laser diode control module in the same PRO8 chassis, the temperature window protection feature switches off the laser diode current if the temperature of the laser exceeds a used-defined temperature window (high and low threshold).

High Power Laser Systems
With up to 64 W of cooling power, the TED8080 is well matched to our LDC8080 Laser Diode Control Module that provides 8 A laser drive current.

High Channel Count Laser Systems
When using our eight channel laser controller (MLC8000 Series), the TED8080 is an ideal choice to temperature stabilize a large number of lasers mounted on a common cold plate.

TEC Safeguards
Damage to the TEC cooler is prevented by setting an adjustable TEC current limit. This can either be set via a recessed potentiometer on the module front panel (hardware limit), via the front panel softkeys or by one of the standard interfaces (software limit).

The TED8000 Series modules meet extremely high standards regarding precision and drift performance and provide a low noise, bipolar output. This enables extremely stable wavelength control and safe thermal load management.

Choice of Temperature Sensors
The TED8000 Series modules can be operated with thermistors, AD590/AD592 IC sensors and LM335 transducers. When operated with a thermistor the thermistor calibration constant can be set so that all applicable settings and displays can be done directly in °C, rather than Ω (ohms). Optionally, the TED8000 Series Controllers can be fitted to ultra low temperature applications (lead-salt lasers), where heating only is required (KRYO option).

Adjustable PID Control Loop
For optimization of laser temperature settling time the P-, I- and D- settings of the temperature control loop can be set via menu-driven softkeys or via one of the remote interfaces.

User-Friendly Controls
The PRO8 display menu allows configuration of any module in the chassis. The operational parameters are easily accessed using mneumonic symbols and simple prompts for user-friendly operations. 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.

Connection Cables
A CAB420-15 cable is required to connect the TED8000 Series Modules to a Thorlabs' Laser Diode Mount. This cable can be ordered separately. It has a length of 1.5 m, PIN Diagrams are shown below.
