OEM Laser Diode & Temperature Controllers
These 100 mm x 160 mm board-level controllers combine a low-noise, low-drift current source with a precise TEC controller. Designed for easy integration into OEM applications, these euro-sized boards are ideal for products or systems where excellent laser emission stability is required. The analog interfaces offer easy access to parameter settings and readout.
These laser diode controllers support constant current (CC) and constant power (CP) modes, as well as all laser and monitor diode polarities (CG/AG). The connected laser interfaces with the controller through a 15-pin D-Sub connector. A fixed-ground-level design significantly improves noise, transient suppression, and output stability. The laser operating current can be modulated by an external control signal.
The built-in temperature controller includes a full PID feedback loop with independent P, I, and D settings, which can be individually optimized. A wide variety of temperature sensors (such as thermistors and the AD335 Temperature Transducer) are supported. A standard 64-pin PCB connector provides access to output signals, analog control inputs, power supply connections, temperature sensors and thermoelectric cooler elements.

Laser Diode Controller Selection Guide
The tables below are designed to give a quick overview of the key specifications for our laser diode controllers and dual diode/temperature controllers. For more details and specifications, or to order a specific item, click on the appropriate item number below.
We also offer a variety of OEM and rack-mounted laser diode current & temperature controllers (OEM Modules, TXP Rack Modules, PRO8 Current Control Rack Modules, and PRO8 Current and Temperature Control Rack Modules).
See the LD Specs and TEC Specs tab for more information.
The ITC100D is a separate display board that can be connected to the ITC100 Series controllers to set the system control parameters. To make the controllers more user friendly, we offer the ITC100F, which is a front panel for the ITC100 Series controllers that covers the control and display boards .
Please note that before installation of the ITC100F can begin, the large analog output control knob must be removed from the ITC100D. To remove the knob, pry off the top surface of the knob with the black indicator line. This will uncover a screw that fixes the knob to the panel. Once the ITC100F is installed, the analog control knob can be placed back into the system allowing for normal operation to continue.
The CAB430 cable can be used to connect the ITC100 Series controllers to Thorlabs' laser mounts. The ITC100P is a replacement 64-Pin female DIN connector that provides access to the full array of Input/Output functions of the ITC100 Series for the laser diode, a photodiode for power monitoring, and the TEC element.
