The Exemplar® Plus is a high performance smart spectrometer utilizing a low stray light unfolded Czerny-Turner spectrograph. It features a highly sensitive TE Cooled back-thinned (BT) CCD detector which is linearly summed for high dynamic range. 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 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.

The Exemplar Plus is available in the following standard configuration: wavelength range of 200-850nm, 25μm slit, a LVF filter, a ruled grating (800mm/250nm), and a spectral resolution of 1.5nm.

Applications:

  • Low Light Level UV to NIR Spectroscopy
  • Raman and Fluorescence Spectroscopy
  • On-line Process Monitoring
  • LCD Display Measurement
  • Gas and Water Analysis
  • LED Characterization
