ST-M833 - Double Dispersive Automated monochromator/spectrograph

- High resolution & high aperture
- Long-focus monochromator in a compact design
- Extremely low stray light
- Full computer control
- Full-Speed USB interface.

The M833 is a unique high-aperture doubled-dispersive monochromatorspectrograph combining high spectral resolution and low stray light in a compact design.

Fully automated, the M833 is controlled from a РС via full-speed USB interface, and contains a turret with three pairs of gratings (grating type and blaze are your choice), up to two input ports and two output ports. Each of the input ports is compatible with our options and accessories– standard and crossed entrance slits, filter wheels, aperture matching units, and optical fibers. Each of the output ports can be completed with either an exit slit or an array detector with a corresponding detector adapter.

The M833i (IMAGING) version allows astigmatism compensation and ensures extraordinary resolution along the exit slit while maintaining ideal line quality. The IMAGING version is arranged by an automated folding mirror which switches radiation between two output ports. This allows the user to obtain the imaging effect at the lateral output port, keeping the standard configuration of the axial output port.

At your request, M833 can be supplied with DLLs and LabVIEW drivers for controlling the instrument via unique software.

ST-MSA-130 - Double Additive/Subtractive Monochromator

- Ease of switching between two operating modes
- Double Monochromator for stray light rejection
- Subtraction & Addition Modes
- Compact & Economical
- High Throughput

The main feature of the MSA-130 Monochromator is its capability to operate in  both addition and subtraction dispersion modes. It is the only instrument in the word capable of providing both modes without any additional alignment and calibration. Addition and subtraction modes are slected by manual switching of a selector knob from the position “Addition” to “Subtraction”, and vice versa.

In the Dispersion Addition Mode, MSA-130 has effective focal length of 260 nm, and extremely low stray light caused by an intermediate slit and carefully calculated optical design.

In the Dispersion Subtraction Mode, MSA-130 serves as a tunable low-stray-light-filter with pass band variable from 0.2 nm to 80 nm. Zero-dispersion spectral range separated by the MSA-130 is determined by the intermediate slit. Central wavelength is set via computer control, by synchronous turning of two identical diffraction gratings. Input, intermediate and exit slits have manual control and smooth micrometrical adjustment of the opening width.

The MSA-130 Monochromator software allows calculation of the FWHM in both operating modes, depending on the set widths of input, intermediate and exit slits.
