Features

• 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.
• 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.
• The M833i in the Imaging mode provides absolute astigmatism compensation and high spatial resolution along the exit slit, meanwhile preserving the ideal line quality.
• 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.
• 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.
• Full computer control: slits, diffraction grating turrets and filter wheels, input/output port switching is controlled by the intelligent and easy-to-use software.
• The SolarLS.LAB software provides automated control over the M833 and its detectors. It allows stitching spectra obtained by several diffraction grating scans in order to get a panoramic spectrum. Many possibilities of spectra processing and analysis are provided as well.
• At your request, DLL and/or VI program modules are supplied for controlling the instrument via the customised software or LabVIEW.

Applications:

• Raman Spectroscopy
• Emission and Fluorescence Spectroscopy
• Analytical Tasks Demanding High Resolution in the Range from UV to IR
• Multi-Channel Spectroscopy

Instrument Configuration

The M833 comprises either one or two input and output ports. Input port may hold either a standard entrance slit, or a crossed entrance slit (optionally). All the spectral slits are automated; their width is adjusted by the instrument software. The slit design also contains a microscrew, which provides the possibility to manually adjust the opening width of the slit knives.

The standard M833 version comprises three pairs of diffraction gratings mounted on two turrets. 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. This allows to bring your real optical system close to the initial optical design and to provide its highest optical quality.

The standard optics comprises spherical and flat mirrors with Al+MgF2 coating optimized for high UV efficiency. Optionally the M833 may contain optics with Al+SiO2 or gold coating for high efficiency in the infrared spectral range.

The M833 output ports may hold either two exit slits, or one exit slit and detector, or two detectors concurrently.

Direct (axial) and lateral (radial) output ports operate alternately. Switching between the output ports is effected by the software with the use of the swinging mirror, which in its operating position directs light to the lateral (radial) output port. The instrument is also available with one output (axial) port. If the radial output port is not used, it is plugged.

The M833 exit slit has 4 mounting holes M2.5 that allow you fixing your own detector to the slit housing, if necessary. Location of mounting holes is shown in the figure below.

Note: To avoid a breakdown of the slit mechanism it is prohibited to fix any units weighing more than 1 kg to the slit housing!
