CRO-MMS MINIATURE SPECTROMETER

The miniature spectrometer CRO-MMS is a complete spectrometer having both high quality optics and proven electronics. The optical system is the well known Carl Zeiss MMS spectral sensor. The electronic system is the proven Cronin system which has been used for many years in line cameras for spectrometer detection array electronics. The combination results in a highly superior spectrometer. Connection to a PC using USB, RS232 or parallel

 

Basic Model

                                        IP68 Waterproof model

Benchtop Model

All CRO-MMS modules are complete just connect to a PC and run.

The electronics include direct computer interface circuit.the detector signal conditioning pre-amp, the A/D converter, data storage, 

These components are integrated into a very compact, robust package. This provides a very stable system, resulting in a high integrity light path with minimum temperature drift. The spectral data acquired are very precise with high signal to noise ratios.

Up to 2048 full spectra can be stored in the spectrometer without needing to download the data to a PC. This enables very fast time resolved spectroscopy.

Long measurements can be made. At 4 ms/scan a measurement of 2048 scans can record spectra continously for 8 seconds
