685-0.5 ComboPak, 500mA/10V Laser, 3A/3.5V TEC

Call How to Buy
685-0.5 ComboPak, 500mA/10V Laser, 3A/3.5V TEC

The 685-0.5 ComboPak offers excellent laser performance, useful for a wide range of laser and LED devices. With 20uA set point resolution and less than 5uA of noise, the 685-0.5 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
    • 500mA / 10V
    • 0.02mA resolution
    • <5 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 685-0.5'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.
