Product details
Double M266-Based onM266The Double Cascade ()
Double cascade monochromator/spectrometer product description:
The monochromator (spectrometer) M266 can be modified to have a dual system M266: in this case, the output slit of one M266 becomes the input slit of the second M266. Due to a larger focal length and increased dispersion, it has better spectral resolution and lower stray light. The dual cascade monochromator/spectrometer can achieve effective transmission from the light source to the monochromator through various options, such as spherical and annular optical elements.
Application of dual cascade monochromator/spectrometer:
1. Emission, fluorescence, and
2. Multi channel spectroscopy
3. Absorption, reflection, and transmission
4. Measurement
5. Analysis tasks from ultraviolet to infrared
