The SuperKontrol graphical user interface is a comprehensive computer control system for all SuperK sources and connected SpectraK accessories. All SuperK and SpectraK products are interfaced to any PC via standard USB connection and allows control of basic functions such as light power control, current or power mode, instant light-on-demand and system reset.  However, the software allows other flexible control functions such as wavelength tuning and scanning, on-board system diagnostics and system log file download. The software can be extended with custom features.
