instruments monochromator-spectrograph are general-purpose instruments which can be used as monochromators or spectrographs with a large flat focal field. The focal length is 200mm, 350mm, 520mm and 750mm. They are completely automated spectral devices. The 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. 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). We have imaging model with the astigmatism-corrected optics what makes these devices applicable in multi-channel spectroscopy. 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. |
