The Exemplar® Plus from B&W Tek is a high performance smart spectrometer that utilizes a low stray light unfolded Czerny-Turner spectrograph. It has a highly sensitive TE Cooled back-thinned (BT) CCD detector, which is linearly summed for high dynamic range.
The Exemplar Plus’s long focal length combined with a high quantum efficiency detector provides excellent data quality across the entire 190-1100 nm spectral range. It has a high signal to noise ratio, which makes it perfect for low light level applications. It also has an integrated shutter that enables dark scan measurements, even while illuminated.
As a member of the Exemplar product line, it features USB 3.0 communication and on board data processing. The Exemplar product line is also optimized for multi-channel operation, which features gate jitter and ultra-low trigger.
As a standard configuration, the Exemplar Plus comes with: a LVF filter, wavelength range of 200 - 850 nm, a spectral resolution of 1.5 nm, 25 µm slit, and a ruled grating (800 mm/250 nm).
The key applications of the Exemplar Plus are as follows:
- Raman and fluorescence spectroscopy
- Low light level UV to NIR spectroscopy
- Gas and water analysis
- On-line process monitoring
- LED characterization
- LCD display measurement
The key features of the Exemplar Plus are as follows:
On-board processing including averaging, smoothing, and dark compensation.
