Focusing
It is absolutely essential to maintain the correct focal distance for every laser marking pro-
cess. Only when in focus will the laser beam achieve the power density necessary for per-
manent and clearly legible marking.
Prior to any marking it is therefore necessary to set the correct focal distance between the marking head and the
workpiece. An incorrect focal distance is the most common cause of poor or even indistinguishable markings.
The focal distance (
A
) is measured between the lower edge of the galvo head (
B
) and the upper surface of the
workpiece (
C
). The correct focal distance depends on the lens used (focal length).
Lens
Focal distance (A)
F-100
~134,6 mm
F-160
~211,6 mm
F-254
~361,6 mm
Use the manual Z-Axis handle or the up and down buttons on the Keypad (see also 7.3 Control
