High aperture ratio (F=1:3.6) allows using the M150 for the widest range of routine purposes, including fluorescence, reflection and transmittance measurements in the wide spectral range from UV to IR, analysis of light sources, multi-channel spectroscopy and other applications.
Low stray light, due to high quality of the optical bench and careful engineering of the instrument housing, provides optimum signal-to-noise ratio.
Up to three diffraction gratings mounted on the automated turret cover a wide spectral range with the use of just one compact device.
Both output ports of the M150 have fully functional flat field 30 x 10mm and allow connecting either two exit slits or an exit slit and a multi-channel detector, or two detectors simultaneously, at your choice.
High degree of the M150 automation provides scanning and change of diffraction gratings, change of order-separating filters, adjustment of entrance slit width and automated background subtraction through shutter control.
Both exit slits of the M150 are equipped with precise mechanisms for slit focusing. Precise and easy detector focusing is provided by detector adapters
The IMAGING Version (Optional) ensures astigmatism compensation for the both output ports. This allows light delivery to the M150 with the set of optical fibers positioned along the entrance slit, as well as acquiring signal from array detectors not only in the Binning mode, but also in the Imaging mode.
The SolarLS.LAB software provides automated control over the M150 and its detector. 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.
DLL program modules andor LabVIEW drivers are supplied at your request; they help to arrange the instrument handling within the general control program of your instrumentation system.

The M150 comprises one input port and two output ports. The input port may hold either a standard entrance slit, or a crossed entrance slit (optionally). The entrance slit is automated; slit opening width is software-controlled.
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 M150 includes a turret of three diffraction gratings. At your choice, the number of gratings can be reduced to one or two.
|M150-III||The standard optics and the turret with 3 diffraction gratings|
|M150-II||The standard optics and the turret with 2 diffraction gratings|
|M150-I||The standard optics and one diffraction grating|
|M150i-III||The Imaging optics (astigmatism compensator) and the turret with 3 diffraction gratings|
|M150i-II||The Imaging optics (astigmatism compensator) and the turret with 2 diffraction gratings|
|M150i-I||The Imaging optics (astigmatism compensator) and one diffraction grating|
The M150 output ports may hold either two exit slits, or one exit slit and a detector, or two detectors simultaneously.
Direct (axial) and lateral (radial) output ports operate alternately. Switching between the output ports is effected manually with the Port Switcher located at the upper cover of the instrument. The switcher moves the folding mirror, which directs light to the lateral (radial) output port. If the switcher is off, light goes to the direct (axial) output port.
The instrument is also available with one axial output port. If the radial output port is not used, it is plugged.
The M150 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!
