Theillumination optics can then be unscrewed by turning anticlockwise.To insert the illumination optics, proceed in the reverse order by screwing it clockwise into the unit untilfinger-tight.Finally, the protective caps can be removed and the sample chamber inserted.After the illumination optic has been exchanged, the currently used optic must be registered in the ZENsoftware. The necessary software interface can be found in the Objectives tool window under theMaintain tab.1 Front system cavity door 4 Protective cap for detection optics unit2 Illumination optics (2×) 5 Detection optics unit3 Protective cap for illumination optics unit (2×) 6 Threaded shaft for illumination optics unit (r and l)Fig. 35 Removing and inserting the illumination optics
