The 9040DA double additive half meter spectrometer has been specifically designed for Raman applications, but also functions as a general-purpose monochromator. Special care has been taken to minimize or eliminate stray light wherever possible. By default the monochromator comes with a single grating kinematic mount. Users can manually swap one grating for another without losing alignment. The system ships with one input slit. Please speak with a Sciencetech sales representative to determine the optimal loadout for your particular system, including additional input and output ports, slits, motorized options, and grating selection.Please note that 2 gratings are required for this system, minimum, but are not included.Please see the technical datasheet for more information.
