SpecWin Light - tailor-made for light measurements

The SpecWin Light software from Instrument Systems was developed for applications where the full functionality of SpecWin Pro is not required. It places particular emphasis on a simple, intuitive interface. SpecWin Light supports the MAS 40, CAS 120 and CAS 140B/CT series of spectrometers from the LED-Station series. With basic functions for measurement, analysis and documentation, this software package is ideal for routine applications in the laboratory and in quality control.


  • Runs under Windows Vista 32Bit, Windows 7 and 10 (32-bit and 64-bit)
  • For MAS 40 (LED-Station), CAS 120 and CAS 140CT/D series spectrometers


  • Spectral analysis of all types of light source
  • LED measurements
  • Display measurements

One particularly useful feature of SpecWin Light is the option to acquire and document a series of measurements. Important set-up options and relevant measurement parameters can be chosen from a list for inclusion in the documentation. Each measurement is then appended to a continuous results table which can be easily exported to Microsoft Excel for further analysis.
