NOTE
When a fluorescence camera is used with indocyanine green, in most cases, the
Volista VisioNIR lighthead exhibits little disturbance in the fluorescence signal in
Standard mode. For a weak signal, or to improve contrast on the screen, the Vis-
ioNIR Boost function can be used to optimise the settings (see Table36). The light-
heads are then automatically set to the 5100K colour temperature, and the central
ring LEDs on the Volista600 are turned off.
NOTE
The Volista VisioNIR Boost is automatically applied to all the lightheads in the con-
figuration.
