Abstract (en)
[origin: WO2008043458A1] The aim of the invention is to provide a method and an assembly for focussing optics, objects and condensers in different types of microscopes, said method and assembly achieving optimal illumination and reproduction conditions for the object planes to be analysed by the optimal tracking of the condenser when the optics or object is or are moved, in particular for analysing thick samples. This is achieved by a method, according to which the focus on an object plane (3) in the object (1) to be analysed remains constant by means of the coupled focussing movement of optics (2) and a condenser or an object (1) to be analysed and the condenser (5), thus illuminating object details on all object planes (3) of the object (1) and matching the illumination and reproduction optical path to one another. The coupled focussing movement for focussing the optics (2) and the condenser (5) or the object (1) and the condenser (5) is maintained either by the decoupling of the condenser movement from the microscope stage or by the decoupling of the condenser movement from the movement of the optics, taking into consideration refractive indices, sample thickness and focus depth in the object (1).
