Triple Monochromator
Model Omni-λ5008Ti
Three finely adjusted imaging monochromators in one instrument. The first two run in subtractive dispersion to suppress stray light and the last two in additive dispersion to build resolution, and the system can be operated as a single, double or triple monochromator.
Geschikt voor
High-end Raman, including low-wavenumber measurement close to the Rayleigh line where a notch filter alone is not enough.
