Monochromator-spectrographs MSO350 series are general-purpose spectral instruments which can be used as monochromators or spectrographs with a large flat focal field. They are completely automated spectral devices with a focal length of 350 mm and F-number of 3.8.
Model MSO3501i and model MSO3504i have the astigmatism-corrected optics what makes these devices applicable in multi-channel spectroscopy.
Automated four-grating turret (model MSO3504 and model MSO3504i) provides a fast switching of gratings with high repeatability of the set wavelength.
In model MSO3501 and model MSO3501i a single-position holder is used for easy manual switching of gratings.
