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