1/2, 1/4 Monochromator/Spectrograph

DK/DKSP 240&480 Direct Digital Drive/ Constant Spectral Resolution

Features:

- Connects to any computer through RS 232/IEEE-488
- 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

 

DK/DKSP 240&480 have the same set-up but with differnet focal length. They are complete computer integrated solution with user friendly commands to control the triple grating turret, motorized slits, and optional motorized filter wheel for quick and easy sorting. The constant spectral resolution(CSR) instrument mode, can used 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 very reliable in its class. Each instrument is calibrated and certified prior to delivery.
