M266 Automated Monochromator/Spectrograph is a compact versatile high-aperture instrument featuring high optical quality and low stray light that can be used as a monochromator and/or as a flat field spectrograph. Two output ports allow connecting to M266 two exit slits, exit slit\detector or two detectors simultaneously.
М266 is completely automated. 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.
М266 contains the embedded active HUB which provides control over the whole system consisting of the monochromator and detectors, from your personal computer via one USB cable only.
Perfect flat field and intelligent software allow panoramic spectra with multiple scanning and replacement of gratings and filters to be easily acquired and put into your analytical report.. M266 provides wide possibilities for processing and analysis of the spectrum: intensity calibration, automatic search and analysis of peaks, spectra calculator, axonometric spectrum, etc.
The М266i (Imaging version) contains a cylindrical folding mirror and provides astigmatism compensation for both output ports, thus ensuring use of M266 with 2D detectors not only in the binning mode, but also in the mode of obtaining a two-dimensional Image
At your request, M266 Automated Monochromator/Spectrograph is supplied with DLLs and LabVIEW drivers for controlling the instrument via individually designed software.
