The standard optics comprises spherical and flat mirrors with Al+MgF2 coating optimized for high UV efficiency. This allows to bring your real optical system close to the initial optical design and to provide its highest optical quality. Since the M833 implements separate control for scanning and grating changing, each diffraction grating, when scanning the spectrum, rotates around an axis passing through its center. The standard M833 version comprises three pairs of diffraction gratings mounted on two turrets. The slit design also contains a microscrew, which provides the possibility to manually adjust the opening width of the slit knives. All the spectral slits are automated their width is adjusted by the instrument software. Input port may hold either a standard entrance slit, or a crossed entrance slit (optionally). The M833 comprises either one or two input and output ports.
Many possibilities of spectra processing and analysis are provided as well.Īt your request, DLL and/or VI program modules are supplied for controlling the instrument via the customised software or LabVIEW. It allows stitching spectra obtained by several diffraction grating scans in order to get a panoramic spectrum.
The SolarLS.LAB software provides automated control over the M833 and its detectors.
Two input and two output ports can be completed with the full set of accessories manufactured by SOLAR LS: standard and crossed entrance slits, order separating filter wheels, aperture matching units and optical fibers, CCD detectors and adapters for them.įull computer control: slits, diffraction grating turrets and filter wheels, input/output port switching is controlled by the intelligent and easy-to-use software. Three pairs of gratings (number of lines per mm and blaze wavelength are tailored to the Customer’s requirements) are supplied in a standard set and ensure the widest range of applications. The M833i in the Imaging mode provides absolute astigmatism compensation and high spatial resolution along the exit slit, meanwhile preserving the ideal line quality. The compact long-focus instrument (f=833mm) with the unique high aperture (F# 1:5.5) enables solving tasks, that demand high spectral resolution, yet occupies little space in your laboratory and, furthermore, is mobile. Extremely low stray light allows the multi-element detector to simultaneously acquire both Stokes and Anti-Stokes components at the distance up to 20 cm -1 from the excitation line (1200 l/mm gratings) without using any Notch or Edge-filters.
