The M266 is a compact versatile instrument with high aperture and low stray light and can be used as monochromator as well as flat field spectrograph. A wide range of options for the input port and two output ports, fully automated control of filters and up to 4-grating turret as well as a wide range of available detectors together with the versatile software provide excellent features for processing and analysis.
Features
- High aperture ratio
- Two output ports
- Completely automated
Applications
- Emission, fluorescence and Raman spectroscopy
- Multi-channel spectroscopy
- Absorption, reflection and transmission
- Measurements from UV to IR
The M266 is our general-purpose high-aperture instrument with high line quality and low stray light performance, featuring 284mm focus and 30x10mm flat field.
Instrument Configuration
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.

The M266 monochromator-spectrograph has a wide range of options and accessories ensuring efficient collection of light from the sample located at a finite distance and in infinity, delivering light to the monochromator with and without an optical fiber, performing effective aperture matching of the optical fiber and monochromator. All the exit slits are equipped with precision focusing devices; and detector adapters allow easy detector focusing. Cassegrain lenses allow collecting light from objects located at a distance of 3.5m to infinity. Adapters PS-2 and PS-3 provide for the collection of light from a closely located sample and its effective input into an optical fiber. PS-2 features high transmittance in the UV range, while PS-3 has the possibility of installing an edge filter.
- Order Separating Filters Wheels
- Aperture Matching Adapters
- Condensers for collecting light into the fiber
- Condensers for collecting light into the monochromator
- Crossed Entrance Slit (optionally installed instead of the Standard Entrance Slit)
- Optical Fibers
- Adapters for attaching CCD detectors
- CCD detectors
- Cassegrain lenses
