SM642 Back-thinned CCD Spectrometer

SM642: The Choice for Low Signal Level Applications

 


- Scientific-grade high performance
- Low dark noise and stray light
- Good dynamic range and high rignal to noise ratio
- High UV Quantum efficiency
- Flexible optical input direct to slit or via fiber
- Designed from the groudn up for a wide range of applications
- High speed data acquisition
- Standard design allows up to 200 - 1050nm range
- Auto shutter for dark condition

 

Spectral Products is offering the new SM642 non TE cooled back-thinned 2048 pixel array CCD spectrometer. The SM642 provides high quantum efficiency in UV and high dynamic range. The detector used in the SM642 has 2048 pixels and helps to get better resolution. It is ideal for UV/VIS/NIR spectrometry that requires high signal to noise ratio and/or high dynamic range. The back-thinned CCD has excellent sensitivity in UV and allows deep UV application, even below 200nm. Well designed housing allows a wide measurement window like from 200nm to 1050nm (smaller measurement window sizes increase spectral resolution and light sensitivity) with low stray light. Standard interface to the SM642 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.
