6.3.1.6 Aiming beam brightness
If a fiber is connected to the NUVOLAS the aiming beam brightness icon automatically
changes to purple. The aiming beam brightness can be changed using the arrow keys. If
the laser is in STANDY-BY mode, the aiming beam brightness fades out after a few
seconds.
6.3.1.7 Counter
The emitted pulses are cumulated. The device counts automatically pulses
triggered by the footswitch or the number of pulses with the set frequency.
The maximum number of pulses is 9999. By pressing the pulse counter box
it will be reset to 0000.
6.3.1.8 Information settings
For your treatment with the NUVOLAS
different statistical values can be used, to
track the power, energy respectively, during
the treatment. The information for the
treatment can be found in the lower area of
the main screen.
The parameters which should be displayed can be chosen by yourself. Therefore, the
information setting icon has to be selected. The parameters are selected if the dot next
to the parameter is colored white.
The following values can be selected:
Frequency in Hz: The shown frequency is generated by pulse length and pulse
pause per second.
Energy in Joule: The shown energy value is the product of the set power and the
actual set exposition time as well as the applied pulses. The
displayed energy changes automatically from milli-Joule (mJ) to
Joule (J) to kilo-Joule (kJ).
Ø Spot size: Shows the current chosen spot size, which is used as basis for
calculation for the density of energy. This option may only be used
for probes.
Energy density: Depending on the spot size the system calculates the emitted
density of energy in J/cm². This option may only be used for
probes.
Average power: Shows the result of set power and actual exposition time in
dependence of the pulse length and pulse pause. The displayed
power changes automatically from micro-Watt (µW) to W.
