The 6340-QCL Quantum Cascade Controller is designed for quantum cascade lasers (QCLs), which operate at a much higher voltage than typical laser diodes, providing up to 15 voltage of compliance. Combine that with excellent current performance, with both a 4 Amp and 2 Amp operating range, as low as 100uA set point resolution and less than 40uA of noise, the 6340-QCL provides a transparent driver that won't interfere with the performance of yourquantum cascade laser .

Dual Range
One of the valable features of the controller is the dual range capability, which allows operation in either a 2 Amp range or 4 Amp range. For applications that need less than 2 Amps, the lower range offers higher accuracy, lower noise, and improved stability, while still maintaining the 4 Amp range for higher power devices.

Ground Loops Eliminated
The controller optically and electrically isolates it's isolated inputs and outputs, preventing device-damaging ground loops. No other driver on the market has this capability.

User Function Keys
The user function keys can be used to quickly select a different configuration state or execute a predefined set of commands. Switch between two different experiments or script repetitive actions…anything you can do manually with the instrument can be programmed to the function key.

At-a-Glance
  • 15V Compliance for QCL devices
  • User selectable 2 Amp or 4 Amp range
  • < 40uA noise
  • 60 Watts of TEC power
  • 0.002°C stability
  • AutoTune automatic PID
  • USB / RS-232 interfaces

Powerful 60 Watt Temperature Controller
In addition to the high performance diode driver, the 6340-QCL adds a 60 watt temperature controller, giving you substantial power for demanding applications. Only need a little bit of power? No problem, because the 6340-QCL works just as well driving 2 watts of power as it does driving 50. Support for all standard sensors (thermistor, RTD, AD590, and LM335) is also included.

AutoTune Automatic PID Calculation
All Arroyo Instruments temperature controllers feature AutoTune for automatic PID calculation. With AutoTune, you no longer need to fiddle with PID parameters to find values that work with your application. Simply hook up your mount, set the appropriate limits, and start the AutoTune process. The instrument will automatically calculate PID parameters that will work with your mount.

Simple User Interface
The 6340-QCL’s user interface is remarkably simple… so easy to use, you’ll have it up and running in no time. Easy-to-read messages, simple menus, and powerful multi-line display make the instrument incredibly easy to use.
