Scanner handpiece options
Scanner handpieces 127 mm, 200 mm
The scanner handpieces are different from the focusing handpieces for normal laser
applications. To avoid confusion, the scanner handpieces are color-coded. In addition, the
connection threads differ to avoid connecting the focusing handpiece to the scanner. The size
of the scanned area and the diameter of the beam focus change depending on the focal length
of the scanner handpiece.
Cycle pause
The field
D5
(Fig. 6-3) displays the time between 2 successive scans. While the foot switch is
activated, you can perform successive scans, enabling you to treat larger tissue areas faster.
The scanner handpiece can be repositioned in the selectable pause time.
The pause time can be set to
OFF
for forced ablation using the scanner. To do this, reduce the
time by pressing the
key until
OFF
appears.
Energy density
The field
D7
(Fig. 6-3) shows the calculated energy density in J/cm² which is derived from the
laser power output, the scan speed and the size of the focal point. The energy density is the
parameter that is important for the effects on the tissue. When the size of the scan shape is
changed, the set energy density is not. This means that the effects on the tissue remain
constant. The range in which the energy density can be adjusted is shown in the following
table.
