The Double Monochromators/Spectrographs include two monochromators which are with fine alignment. Double Monochromator can operate as either an additive or subtractive dispersion mode. As the additive dispersion mode, the double monochromator/ spectrograph spectral resolution double boost, suitable for high resolution measurement. As the subtractive dispersion mode, the double monochromator/spectrograph stray light can be reduced effectively, suitable for weaker signal detection, such as Raman spectra measurement. Double and triple monochromators can operate as either an additive or subtractive dispersion mode.
- Use additive dispersion mode for high resolution measurement.
- Use subtractive dispersion mode for weaker signal detection, such as raman spectra measurement.

The triple monochromator is consisted of three image calibration monochromators by fine adjustments. The first two monochromators connected in subtractive dispersion mode to reduce stray light; the last two monochromators connected in additive dispersion mode to improve the resolution. The triple spectrometer is flexible for use in single, double and triple monochromator operation. Thanks to its tunable wavelength and adjustable notch, the triple spectrometer is mainly used for high-end Raman spectrum measurements, such as ultraviolet excitation Raman spectrum and low wavenumber Raman spectrum. Double and triple monochromators can operate as either an additive or subtractive dispersion mode.
- Use additive dispersion mode for high resolution measurement.
- Use subtractive dispersion mode for weaker signal detection, such as raman spectra measurement.
