IMAGING monochromator-spectrographs of MSDD1000 series
MSDD1000 – fully automated imaging monochromator-spectrograph with effective focal length of 1000 mm and high F/number 1/5.9. Optical layout of double dispersion is a distinctive feature of the instrument.
Doubling of dispersion is equivalent to doubling of effective focal length only from a point of view of improvement of spectral resolution. Besides, this optical layout provides reduction of stray light and retention of a high N/A which is inherent to devices without doubling of focal length. Unlike double monochromator-spectrographs, MSDD1000 overall dimensions are not doubled. MSDD1000 is comparable to MS350 in dimensions. Thus, the advantages of MSDD1000 are very high spectral resolution, low level stray light, a high N/A by its compactness.

Monochromator-spectrographs of MS series
SOL instruments presents the state-of-the-art instruments for spectroscopy: classical Imaging Cherny-Turner monochromator-spectrographs of MS series. MS series comprises two groups: the middle focus, high-aperture, compact devices; and the long-focus – more than half a meter – high resolution devices with a large flat focal plane. MS series features are: precise optics, high spectral resolution, precise focus position, and full automation.
