User Guide

The collimation of focusing optics D50 has a focal length of
100 mm or 125 mm. The focal length of the collimation deter-
mines the dimensions of the focusing optics D50.
If collimation is set to zero, the focus position will correspond to
the details in the dimensional drawing.
The focusing optics can be defocused by means of the setting
ring. By defocusing the laser beam the focal point can be
placed below or above the workpiece surface to be processed
while the working distance remains the same.
The cover plate protects the setting ring from undesirable adjust-
ment.
The scale is applied in mm increments and the focus is moved
variously depending on the focal length of the lens (see "Adjust-
ing the focal position", pg. 4‐6).
■
Positive values: Focal point is above the workpiece surface.
■
Negative values: Focal point is below the workpiece surface.
