    摘要: The invention relates to a method and to an arrangement for operating a dynamic nano focusing system for use thereof in the field of microscopy, interferometry or similar applications, wherein the nano focusing system comprises a lever-transmission piezo actuator and a frictionless guide based on a resiliently deformable solid body joint which is connected to a mounting unit, in particular for a lens, in order to implement the desired adjustment paths for the focusing. According to the invention, in order to increase the dynamics during the focusing process, a secondary fine adjustment movement is superimposed on the primary adjustment movement, said secondary fine adjustment movement having a smaller adjustment path but higher frequency than the primary adjustment movement, wherein, when the fine adjustment is carried out, a determination is made as to whether the focusing result changes, in order to specify according thereto the amount and/or the direction of the primary adjustment movement.

    摘要: A specimen and an objective lens can be quickly brought close together or separated without an operator being concerned about the positional relationship between the specimen and the objective lens, and once the correct positional relationship is established, the focal position can be finely adjusted. The invention includes a first focusing mechanism for moving the objective lens in an optical axis direction relative to the specimen so as to approach the specimen or withdraw therefrom; a second focusing mechanism for displacing an internal optical system in the optical axis direction, and a switching device for switching between operating the first focusing mechanism and operating the second focusing mechanism when the objective lens is disposed at a predetermined switching position.
