Cart touchscreen.
Firefly Black Point
Note: Firefly Black Point control is available only in Sensitive mode.
The Firefly Black Point slider adjusts the minimum level (threshold) of the green fluorescent signal
that is displayed. It can improve the signal-to-noise ratio when observing features with low
fluorescent signals.
Use of the Firefly Black Point slider at higher settings may reduce visibility of low fluorescent signals
in order to improve signal-to-noise ratios, which could result in unplanned removal of healthy
tissue. To make sure you have a sufficient view of low fluorescent signals, adjust the Firefly Black
Point slider across a broad range of settings before you select a specific setting.
Scroll down within the Firefly section of the Settings screen until the Firefly Black Point slider is
visible (Figure 31). Moving the slider to the right increases the threshold, hiding low fluorescent
signals. Moving the slider to the left shows more fluorescent signals.
• When the Firefly Black Point slider is set to 0%, all fluorescent signals are displayed (more
green, less black background).
• When the Firefly Black Point slider is set to 100%, weak fluorescent signals are filtered out
(less green, more black background) to reduce background noise and unwanted reflection
of near-infrared illumination.
