Abstract (en)

[origin: WO0163602A1] The invention relates to an optical scanning head (1) in which, for the stabilization of the position with regard to the rotational movements caused by at least one translational adjuster element (3), the positions of the center of gravity (8) of the scanning head (1) and the point of action (9) of the resulting overall adjusting force (13) of the at least one adjuster element (3) are equalized or can be equalized during operation with respect to a certain translational direction for a corresponding translational adjusting movement of the optical scanning head (1). The invention further relates to a corresponding method for carrying out such an equalization that comprises the following steps: determining the position of the center of gravity (8) of the optical scanning head (1); determining the position of the point of action (9) of the resulting overall adjusting force (13) of the at least one adjuster element (3) with respect to a certain translational direction for the corresponding translational adjusting movement of the optical scanning head (1); and equalizing the positions of the center of gravity of the optical scanning head (1) and the point of action (9) of the resulting overall adjusting force (13) of the at least one adjuster element (3).
