Call How to Buy
685-01 ComboPak, 1A/10V Laser, 3A/3.5V TEC

The 685-01 ComboPak offers excellent laser performance for pump lasers, higher power LEDs, and other devices requiring up to 1A of drive current. With 20uA set point resolution and less than 50uA of noise, the 685-01 provides a transparent driver that won't interfere with the performance of your laser or LED devices. Couple that with a high performance TEC controller that supports excellent long term stability and high resolution.

Develop with a ComboSource,
Deploy with a ComboPak

The ComboPak is command-set compatible with the ComboSource and also features the same laser and TEC interfaces. This means you can start your development with the ComboSource, a robust benchtop instrument with a full user interface and display, then move to the lower cost ComboPak as you roll out the application to production or your end-users.

At-a-Glance
  • Laser
    • 1A / 10V
    • 0.05mA resolution
    • <10 uA noise
    • Analog modulation
  • TEC
    • 3A / 3.5V / 10.5W
    • Thermistor input
    • Fully adjustable PID
  • USB interface

Analog or Computer -- Your Choice
The 685 Series ComboPaks provide both a robust analog interface as well as USB computer control for precise remote operation (you can even use both interface simultaneously). The analog interface provies on/off control and status, while the computer interface provies complete control over all operating parameters.

Analog Modulation
The 685-01's analog interface supports modulation rates up to 100kHz.

Simple Multi-Channel System
Using the 1402B-RM Rack Mount Tray, you can quickly rack groups of 3 or 5 Paks into a rack for a quick multi-channel system.

Universal AC Input
The ComboPak features a universal AC input, eliminating the need to reconfigure the instrument when moving your application internationally.
