AUTOMATED MONOCHROMATOR-SPECTROGRAPH M522
FEATURES
M522 is a long-focal automated universal monochromator-spectrograph that is characterized with a high line quality and low-level stray light.
DESCRIPTION
High aperture ratio (F=1:3.8), low stray light and perfect line quality enable successful use of the M522 in a wide 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.
The М522i in the Imaging mode provides absolute astigmatism compensation and high spatial resolution along the exit slit, meanwhile preserving the ideal line quality.
Fully automated control. Scanning and changing of diffraction gratings, order separating filters, adjustment of slit width and selection of an output port are performed automatically and controlled via the intelligent and easy-to-use software.
An automatic shutter provides for automatic background (dark current) subtraction, along with detector protection against excessive illumination from the light source.
Two output slits in М522 feature precise slit focusing units.
Detector adapters in M522 feature ability for fine through focus adjustment.
The SolarLS.LAB software provides automated control over the M522 and its detector. It allows to stitch 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.
DLLs and LabVIEW drivers can be supplied at your request, allowing to control the instrument via individually designed software.
Applications
Emission and Fluorescence Spectroscopy
Absorption, Reflection and Transmission measurements
Multi-Channel Spectroscopy
Analytical Tasks Demanding High Resolution in the Range from UV to IR
Configuration
The M522 contains a maximum of two input ports and two output ports. Either a standard input slit is installed on the input port, or an optional crossed input slot. All spectral slits are automated, the width of the slits is software-adjustable. Structurally, the slit also contains a micro-screw and has the ability to manually adjust the slit width. Depending on the modification, the M522 may contain either a turret of four diffraction gratings, or one diffraction grating in the holder.
