DK240: Direct Digital Drive/Constant Spectral Resolution
- Connects to any computer via RS 232 or IEEE-488.
- Motorized slits
- Triple-grating turret allows high-efficiency scanning across a board spectral range
- May be factory configured as a monochromator or spectrograph
- Scans in both directions and with Constant Spectral Resolution (CSR)
- Integrates with SP filter wheel for automatic filter switching.
- Suitable for fluorescence and absorption studies, detector characterization, thin film measurements, etc.
The Digikröm DK240 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 for the change in dispersion with wavelength to maintain a constant spectral bandpass.
Rugged cast construction, A-Thermal design, and SP direct grating drive make this unit the most repeatable and reliable in its class. Each instrument is calibrated and certified before delivery.
