MAS 40 – High-quality, robust CCD spectrometer technology

The compact, low cost MAS 40 mini-array spectrometer has a wide range of uses in industrial quality control as well as in research and development. It satisfies all Instrument Systems guaranteed quality requirements for spectroradiometers for the absolute measurement of light radiation. This includes calibration with the desired measurement adapter that is traceable to national and international standardization bodies such as PTB or NIST.

The MAS 40 is compatible with the complete set of Instrument Systems accessories via an optical fiber. This opens up a broad range of applications in photometry. Since the power supply is connected via USB, the MAS 40 is ideal for mobile use on the laptop.
