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.

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 interfaces simultaneously). The analog interface provides on/off control and status, while the computer interface provides 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 1402C-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.
