The CTDK240 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.Connects to any computer via RS232 or IEEE-488.
Motorized slits.
Triple-grating turret allows high efficiency scanning across a broad 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.
