METHOD FOR SUPPORTING AN ADJUSTMENT OF A BEAM EXPANDER, ADJUSTMENT SUPPORT DEVICE AND BEAM EXPANDER

摘要

The invention relates to a method for supporting an adjustment of a beam expander (100), which has a holding tube (102), having a light entry opening (104) and a light exit opening (108), and which has at least one optical element (200, 202, 204) arranged in a beam path between the light entry opening (104) and the light exit opening (108) for changing the diameter of a beam (106) coupled in via the light entry opening (104). In the method, a target position of the beam (106) along an optical axis (110) of the beam expander (100) is determined by sensing a reference surface (114) coupled to the holding tube (102), and an actual position of the beam (106) along the optical axis (110) is determined by sensing the energy distribution of the beam (106) with respect to a cross-sectional area of the holding tube (102). A deviation value representing a deviation between the actual position and the target position is determined by comparing the actual position with the target position. Finally, by using the deviation value, support information (124) for supporting an operator in the adjustment is output.
