Monochromator M266 is our general-purpose high-aperture instrument with high line quality and low stray light performance, featuring 284mm focus and 30x10mm flat field.
HIGH APERTURE RATIO (F=1:3.8)
TWO OUTPUT PORTS
THE M266I VERSION (IMAGING)
M266 IS COMPLETELY AUTOMATED
High aperture ratio (F=1:3.8), low stray light and perfect line quality enable successful use of the M266 in a wide range of applications.
Two output ports allow connecting to the M266 either two exit slits, exit slit/detector or two detectors concurrently.
The M266i version (Imaging) features an astigmatism compensator for both output ports, thus promoting the use of the M266 with matrix detectors in the multi-channel spectroscopy, not only in the binning mode, but also in the 2D-image mode.
M266 is completely automated. Spectrum scanning along wavelengths, change of gratings and order separating filters, adjustment of slit width and selection of an output port are performed automatically, guided by 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.
The SolarLS.LAB software provides automated control over the monochrometer M266 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 andor LabView drivers are supplied with the M266 for controlling the instrument via the customised software or LabView.

Analytical Tasks from UV to IR
The M266 comprises one input port and two output ports. The 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 knives.
Depending on modification, the M266 may contain either a turret with four diffraction gratings, or one grating in the holder.
|M266-IV||The standard optics and the turret with 4 diffraction gratings|
|M266i-IV||The Imaging optics (astigmatism compensator) and the turret with 4 diffraction gratings|
|M266-I||The standard optics and one diffraction grating|
|M266i-I||The Imaging optics (astigmatism compensator) and one diffraction grating|
The standard optics comprises spherical and flat mirrors with Al+MgF2 coating optimised for high UV efficiency. Optionally the device may contain optics with Al+SiO2 or gold coating for high efficiency in the infrared spectral range.
The M266 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 M266 exit slit has 4 mounting holes M2.5 that allow you fixing your own detector to the slit housing, if necessary. Location of the 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 1kg to the slit housing.
