The MZDD350i model from SOL instruments is a double monochromator with zero dispersion consisting of two imaging monochromators MS3504i configured in one construction and the exit slit of the first monochromator is the entrance slit of the second monochromator. The device is fully automated. A set of four gratings and smoothly adjustable slits allow to operate in a wide spectral range (ultraviolet, visible and IR spectral regions) with a required bandpass.
Features of MZDD350i double monochromator are: wide spectral range (UV, VIS, IR), low level of stray light, high aperture, high wavelength accuracy and repeatability, as well as full computer control. MZDD350i is ideal for Raman spectroscopy, spectroscopy of pulsed light sources, measurements of the CCD detectors quantum efficiency, and for various spectral measurements in ultraviolet, visible and infrared regions where tunable monochromatic light is wanted.
