CHAPTER 1 - HARDWARECarl Zeiss User Interfaces Lightsheet Z.146 000000-1790-528 02/20133.9.2 Removing and Inserting the Detection Optics UnitIn order to remove the detection optics unit (Fig. 36/3) located in the rear zone of the system cavity, thesample chamber must first be removed (see Section 3.4). To prevent damage to the illumination opticsunits, these must also be removed (see Section 3.9.1). Secure the appropriate protective cap (Fig. 36/4)onto the detection optics unit.Grab the detection optics unit as close as possible to the base and remove it by turning anticlockwise.Caution: the detection optics unit is heavy.To insert the detection optics unit, it must be screwed in a clockwise direction without exerting force.Subsequently the protective cap should be removed before re-inserting the illumination optics unit andthe sample chamber.After the detection 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.Each detection optic unit is labeled with an individual serial number. It ensures that the specificcalibration file for this lens, necessary for optimal performance, is used when identified within thesoftware. The calibration file is created by a Carl Zeiss service personnel representative during systeminstallation, or when a detection optic is newly purchased. Ensure that the correct detection optic unit ischosen in the ZEN software interface, based on its name and the specific serial number of the detectionoptic in use.1 Front system cavity door2 Threaded shaft for detection optics unit3 Detection optics unit4 Protective capFig. 36 Removing and inserting the detection optics
