    • Internal controller connects to any computer via RS232 or IEEE-488. Hands-off control of three slit assemblies and two grating turrets.
    • Scans in both directions and with Constant Spectral Resolution (CSR).
    • Triple-grating turrets allows high efficiency scanning across a broad spectral range.
    • Additive dispersion increases resolution and reduces stray light for Raman and fluorescence studies, subtractive dispersion minimizes broadening of pulse sources.
    • Integrates with SP filter wheel for automatic filter switching.
    • May be factory configured as a monochromator or spectrograph.
