Monochromator-spectrograph of MS series



MS series

SOL instruments presents the state-of-the-art instruments for spectroscopy: classical Imaging Cherny-Turner monochromator-spectrographs of MS series.

Our MS series monochromator/spectrographs comprise 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. All instruments are fully automated. The choice of a particular instrument depends on the purpose of measurement.

The middle focal devices have been designed especially for operation with very low levels of light signals, they are mostly applicable for measurements in wide spectral range at different wavelengths at once. This group includes MS200 and MS350 instruments, which are ideally suitable for majority of applications.

A long focal device is the one you need if such features as high resolution, accuracy, reproducibility, size of a scanning step – are of principal demand. Thus, a choice should be made among the devices in another group of instruments: MS520, MS750 and MSDD1000.
