The Exemplar® LS is a smart CCD spectrometer optimized for low straylight by utilizing an unfolded Czerny-Turner spectrograph. It features on board data processing, USB 3.0 communication, and temperature compensation. The Exemplar LS is also optimized for multi-channel operation, featuring ultra-low trigger delay and gate jitter. Additionally, the Exemplar LS features a 2048 element detector and built-in 16-bit digitizer with greater than 2.0 MHz readout speed.
The Exemplar LS is available in the following standard configuration: wavelength range of 200-850nm, 25μm slit, an LVF filter, a ruled grating (800mm/250nm), and a
spectral resolution of 1.5nm.
SMART: On-board processing including averaging, smoothing, and dark compensation
SPEED: Acquires and transfers more than 900 spectra per second at an integration time of 1050µs
SYNCHRONOUS: Supports up to 32 devices with ultra-low trigger delay (35ns) & gate jitter (+/- 5ns)
