INSTRUMENT SYSTEMS CAS 140D SPECROMETER

New Reference Spectrometer For Spectral Measurement

Instrument Systems CAS 140D, the 4th generation spectrometer combines with all the advantages of the CAS 140CT in terms of measurement accuracy and reliability with sustainable technical optimization for increased repeatability and stability in every environment. As a result, it offers even more versatile applications – from the reference instrument in national calibration laboratories to continuous production. A wide range of accessories complement the spectrometer to create a complete system for a wide range of spectroradiometric and photometric measurement tasks.  

Automatic accessory identification of the CAS 140D enables quick and easy changing of a wide range of measurement adapters. In production environments the new “plug & play” principle ensures high process reliability. The system automatically recognizes the connected accessories and ensures that only currently valid calibrations are used.

Another new feature of the CAS 140D is the interchangeable interface between the spectrometer and control computer. Depending on the measurement task, the interface can be easily replaced via plug-in modules with USB, PCIe or Ethernet interface.

The CAS 140D is ideally suited for all requirements in spectral measurement and photometry. The versatile fiber connector, a broad range of accessories and the balanced software functions enable a wide range of system solutions that cover all regular measurement tasks.
