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.

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.
