Spot size selection
Spot size is adjusted by turning the adjustment
ring on the SLA (Figure 34). You may observe
the spot size value from the GUI screen while
adjusting the spot size from the SLA. The spot
size value range depends on the magnification
of the selected contact lens, often also
referred to as Laser Magnification Factor.
Spot size view on GUI
As explained, the available spot size depends on
selected parameters and maximum optical power
of the laser. Figure 35 gives an example of the
notification when spot size is adjusted too large
and laser power limit is exceeded. In this case,
the spot must be adjusted lower until the red
warning message disappears and the treatment
parameters can be confirmed.
Figure 34. The spot size is selected by rotating the
grip wheel on the SLA.

The spot size given by the Graphical User Interface (GUI) includes the contact lens
magnification and indicates the diameter of the actual spot in the retina of the patient.
WARNING
Aiming beam
In addition, you can control the aiming beam
by setting the aiming beam to on, off or pulsed
mode. You can also set the aiming beam
brightness to desired level. The aiming beam
laser is a class 2 laser and corresponding
laser safety precautions must be followed.
Please make sure the spot is properly in focus before
starting a treatment. See section 4.4.4 for instructions.
In case the aiming beam is not visible, do not treat the patient. Disable
the device from use and contact the manufacturer for service.
