Typically， the TriVista is utilized as a double or triple system. When the light beam is passed sequentially through 2 or 3 stages and the gratings coherently move together with very high precision. Some common reasons researchers choose a double or triple system are the high spectral resolution and the high stray light rejection.

Figure 1C

These important parameters can be accomplished by utilizing different modes of TriVista operation:

1. Additive mode gives high spectral resolution and high linear dispersion.

2. Subtractive mode gives high stray light rejection.

Resonance Raman Spectroscopy

Instead of fluorescence， some types of colored molecules produce strong Raman scattering at certain conditions. This effect was called Resonance Raman.

X-Ray Spectroscopy

X-ray absorption spectroscopy is an element-specific probe of the local structure of elements in a material.

Stimulated Raman Scattering

Stimulated Raman scattering takes place when an excess of Stokes photons that were previously generated by normal Raman scattering are present or are deliberately added to the excitation beam.
