MS750 series 

Monochromator-spectrograph MS750 series are devices with 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 spectrographs.

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

M750 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 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.

Monochromators?spectrographs of MS750 series have one input port and two output ports. Selection of an output port is realized with an automated mirror. Either output spectral slits or multi-channel detectors can be installed on each of the output ports.

Extremely high spectral resolution ? better than 0.02 nm for grating 1200 grooves/mm,makeS monochromators-spectrographs of MS750 series ideal devices for high resolution spectroscopy: Raman spectroscopy, laser-induced breakdown spectroscopy and also for multi-channel spectroscopy ? models MS7501i and MS7504i, which provides extremely high spatial resolution along the slit heigh. 

Optical scheme is optimized for:

• minimization of coma aberration over the whole operating spectral range
• elimination of the light re-entrance from two basic mirrors
• elimination of the light re-entrance between mirrors
  of the instrument and input windows of the detectors in the focal plane
• a large plane focal field for the whole operating spectral range
• astigmatism compensation for the whole operating spectral range
  by means of special correcting optics (for imaging modifications MS7504i and MS7501i)
