DK480 1/2m FL Monochromator and Spectrograph
The Digikröm 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 repeatable and reliable in its class. Each instrument is calibrated and certified prior to delivery.
-Triple-grating turret allows high efficiency scanning across a broad spectral range with motorized slits
- 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
- Connects to any computer via RS 232 or IEEE-488.

It is the ability of the device to return to the same wavelength. The measured wavelength by the equipment should not drift over the range provided.
It is a measure of the deviation of the wavelength when the standard wavelength is measured. You would expect the vaue of the wavelength to be the standard value with the deviation everytime you take a measurement.
It is the the ability of the instrument to differentiate between different
wavelength of light.
It is the rate which the wavelength is being read.
The range of frequencies or wavelengths that can pass through the slits
