Monochromator-spectrographs of MS750 series are long-focus devices with a large flat focal field, combined with a high-intensity, accuracy and spectral resolution. They are completely automated spectral devices with focal length of 750 mm and F-number of 1/8.9, which can be used both as monochromators and as spectrographs.
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).
MS750 series monochromator-spectrographs are based on Cherny-Turner asymmetric scheme, aberrations are minimized and re-reflections from diffraction gratings and mirrors are excluded.
Model MS7501i and model MS7504i have the astigmatism-corrected optics what makes these devices applicable in multi-channel spectroscopy.
Automated four-grating turret (model MS7504 and model MS7504i) provides a fast switching of gratings with high repeatability of the set wavelength and the vertical image.
In MS7501 and MS7501i models a single-position holder is used for easy manual switching of gratings.
A wide choice of changeable gratings gives the best combination of high energetic efficiency and maximal spectral resolution for different spectrum areas.
Monochromator-spectrographs of MS750 series have one input port and two output ports. Installation of an output port is realized with an automated mirror.
Extremely high spectral resolution – better 0.02 nm for grating 1200 grooves/mm and better 1 pm for echelle grating – makes monochromator-spectrographs of MS750 series the ideal devices for high resolution spectroscopy: Raman spectroscopy, laser-induced breakdown spectroscopy, multi-channel spectroscopy (models MS7501i and MS7504i provide extremely high spatial resolution along the slit height).
