BOZEMAN, Mont., Oct. 11, 2011 — For precision USB laser diode and temperature control, Wavelength Electronics is offering the USBKIT interface board and software package. The bus-powered USB 2.0 interface board is easily wired using onboard screw terminals, and the QuickConnect virtual control panel provides out-of-the-box functionality with strip chart graphs that show real-time laser system status.
One laser diode driver and one temperature controller can be simultaneously operated with the interface board, and multiple USBKITs can be attached to the same computer, enabling control of complex systems.
A factory-modified National Instruments multifunction input/output card includes digital-to-analog conversion for remote set-point control, and auxiliary analog-to-digital conversion for increased versatility. The software controls one laser diode driver and one temperature controller and features graphing and data logging. The setup configuration can be saved for repeating experiments or manufacturing testing. The QuickConnect software includes on-screen wiring diagrams for the connected Wavelength Electronics modules, making setup a snap.
Using the full-featured graphic interface, the user can set the desired load temperature as a voltage or a temperature, and maximum and minimum temperature limits can be established as well as whether laser diode current is disabled if temperature limits are exceeded. Temperature sensor calibration is easy with the built-in resistance-to-temperature conversion functions.
The software provides control of the laser drive current in constant current mode, or photodiode current in constant power mode. Photodiode current is easily converted to laser output power, and the drive current limit is displayed on-screen.
Two strip charts graph data as a function of time. Raw voltages as well as translated current and temperature values are available. One graph is associated with data from the temperature controller, and the other displays laser diode controller data. Auxiliary monitors can be associated with either graph, and all data can be logged whether it’s displayed or not.
Program customization is available for applications that require additional functionality.
