Exemplar Plus LS
Low Straylight Smart CCD Spectrometer
The Exemplar® Plus LS is a high performance smart spectrometer utilizing an aberration corrected concave holographic grating, to minimize stray light. Its long focal length, coupled with a high quantum efficiency detector, provides superior data quality over the entire 190-1100nm spectral range. The Exemplar Plus LS features a high signal to noise ratio, making it ideal for low light level applications, and also features a built-in shutter allowing for dark scan measurements, even while illuminated. As a member of the Exemplar product line, it features on board data processing and USB 3.0 communication. The Exemplar product line is also optimized for multi-channel operation featuring ultra-low trigger delay and gate jitter.
Standard spectral configurations range from 180nm - 1050nm and resolutions range between 0.6nm and 6.0nm. Custom configurations are available for OEM applications.
