MS350 Series monochromators–spectrographs a general-purpose instruments which can be used as monochromators or spectrographs with a large flat focal field. They are completely automated spectral devices with focal length of 350 mm and F-number of 1/3.8.

High-quality optics and wide choice of diffraction gratings provide devices operation in a wide range from 185 nm up to 60 µm (depending on the selected grating).

M350 Series monochromator-spectrographs are based on Cherny–Turner asymmetric scheme that allows to minimize of aberrations and exclude spectra re-entrance from diffraction gratings and mirrors.

Model MS3501i and model MS3504i have the astigmatism-corrected optics what makes these devices applicable in multi-channel spectroscopy.

Automated four-grating turret (model MS3504 and model MS3504i) provides a fast switching of gratings with high repeatability of the set wavelength and the vertical image.
