COMPUTERIZE THE WAVELENGTH ADVANTAGE
Expand the capabilities of your Wavelength controllers with the USBKIT and QuickConnect™ software. The USBKIT provides convenient computer control of most Wavelength chassis mount controllers and evaluation boards at a surprisingly low price. The QuickConnect™ software provides an intuitive virtual control panel that allows you to leverage the low-noise, high-stability laser diode and temperature control capabilities of Wavelength’s components to save time and money. The QuickConnect™ software is compatible with x86 (32-bit) and x64 (64-bit) PCs.BIG FEATURES IN A SMALL PACKAGE
The USBKIT loads many features into one small package, making it a terrific value-add for your laser lab or manufacturing floor.- The USB board includes D/A for remote setpoint control and A/Ds for monitoring actual temperature or current.
- The software provides control of one laser diode driver, one temperature controller, an auxiliary monitor, and full graphing and datalogging of selected parameters.
- Multiple USBKITs can be attached to the same computer, allowing for control of complex systems.
- Setup configurations can be saved for repeating experiments or manufacturing testing routines.
- The QuickConnect™ software includes on-screen wiring diagrams for the selected Wavelength modules, making set-up a snap.
- Two strip charts graph laser and temperature data as a function of time. Selected data can be continuously logged.
PLUG-IN CONVENIENCE FOR OEMS
Build the USBKIT into your OEM laser system and enjoy the convenience of closed-cover system calibration and troubleshooting—all you need is the USB cable that comes with the USBKIT.LEARN MORE
