  • Wide dynamic range and high signal to noise ratio
  • High Ultra-violet Quantum efficiency
  • Flexible optical input direct to slit or via fiber
  • Designed from the ground up for a wide range of applications
  • High speed data acquisition
  • Standard design allows up to 200-1050nm range
The Choice for Low Signal Level Applications

Spectral Products is offering the new SM303 TE cooled back-thinned 1024 pixel array CCD spectrometer.

The SM303 is ideal for UV/VIS/NIR spectrometry that requires very high signal to noise ratio and/or high dynamic range, like fluorescence, Rama, LED property testing applications. The back-thinned CCD has excellent sensitivity in UV and allows deep UV application. Well designed housing allows up to a 850nm measurement window from 200nm to 1050nm (smaller measurement window sizes increase spectral resolution and light sensitivity) with very low stray light. The TE cooled detecor also help to measure very low light signals by reducing the noise level in long integration times.

Thanks to the hidynamic range and the low noise, the SM303 is also ideal for radiometric measurement applications.

Standard interface to the SM303-Si is a USB 1.1/2.0 compatible interface with 16-bit. Software support includes a SDK and DLLs for dedicated applications development and our SM32Pro Windows-based spectral acquisition and analysis software.


  • SM32Pro - Windows® 95, 2000, XP, 7 based software (supporting 32bit & 64bit) for data acquisition and analysis
  • Transmission, reflectance, and absorbance measurements
  • Data export, zoom in and out, spectrum overlays, and many more features
  • Color analysis tools included
  • Signal average and integration time control
  • DLL libraries available for easy user software development in DOS and Windows®
  • VC++/VB/Labview examples available
