The Digikrom DK480 is a complete computer integrated solution. Easy to use commands control the triple grating turret， motorized slits， and optional motorized filter wheel for quick and easy sorting. Instrument mode can be set for constant spectral resolution (CSR)， where the slit width is automatically modified to compensate in the change in dispersion with wavelength to maintain constant spectral bandpass.
Rugged cast construction， A-Thermal design， and SP direct grating drive make this unit the most repaetable and reliable in its class. Each instrument is calibrated and certified prior to delivery.
