MSA-130 is a high-aperture double monochromator with the focal length of 130 mm, which operates in the modes of both addition and subtraction of dispersions. The monochromator operation modes are changed by switching of a selector knob from the position “Addition” to “Subtraction” and vice versa.

In the Dispersion Addition Mode the instrument is the analog of a standard monochromator with the doubled resulting focal length of 260 nm and extremely low stray light.

In the Dispersion Subtraction Mode MSA-130 ensures zero dispersion for the spectral range, whose width is determined by the intermediate slit, and the central wavelength is set by synchronous turning of two identical diffraction gratings. The instrument serves as a filter tunable in the range 190-1300nm with the pass band changed from 0,2nm to 80 nm, and low stray light level.

Control of diffraction gratings is made from a computer via High-Speed USB interface. Input, intermediate and exit slits have manual control and smooth micrometrical adjustment of the opening width.

The MSA-130 software allows calculating the spectral width of the line separated by the monochromator in the both operating modes depending on the set width of input, intermediate and exit slits.

APPLICATIONS

• Raman spectroscopy
• Emission and fluorescence spectroscopy
• Transmission/Absorption/Reflectance Measurements

Double Dispersive Automated
Monochromator/Spectrograph M833

M833 Standard version is a unique high-aperture double dispersive monochromator/spectrograph whose compact design combines high spectral resolution intrinsic for long-focus devices and extremely low stray light peculiar to
double schemes.

The М833i version (Imaging) ensures absolute astigmatism compensation and extraordinary resolution along the exit slit while maintaining ideal line quality. IMAGING version is arranged by an automated folding mirror switching radiation between two output ports. This allows obtaining Imaging effect at the lateral output port, keeping the standard configuration of the axial output port.

The unique combination of custom settings obtained in one compact and reliable unit will provide you with new experimental opportunities and let you use the potential of the system you already have to much fuller extent.

APPLICATIONS

• Raman spectroscopy
• Emission and fluorescent spectroscopy
• Analytical tasks in the range from UV to IR
• Multi-channel & imaging spectroscopy
