PUTTING THE INSTRUMENT INTO OPERATIONAxio Vert.A1 Mounting Optional Components Carl Zeiss05/2012 431030-7044-001 65If the installation of filters not provided withdirection markings (arrows) proves necessary, werecommend that the procedure below be followed:Be sure to install filters with reflecting, dielectriclayers in such a way that the reflecting layer(Fig. 3-29/6) in the excitation filter (Fig. 3-29/5)points outward (in relation to the reflectormodule). In the barrier filter (Fig. 3-29/1), thereflecting layer(Fig. 3-29/2) must point inward(Fig. 3-29).In mounting position, the reflecting layer(Fig. 3-29/4) of the beam splitter (Fig. 3-29/3) mustpoint downward.The arrows (Fig. 3-29/7) mark the illuminationbeam path or the imaging beam path.3.3.4 Changing the Beam Splitter in the FL P&C Reflector ModulePlease, proceed with utmost care in mounting the filters and the beam splitter to avoiddamaging and soiling optical components.We recommend that you order fully fitted FL P&Creflector modules from Carl Zeiss, as changing thebeam splitter is a demanding operation.Proceed as follows when changing the beamsplitter:• Remove the FL P&C reflector module from thereflector turret. (See also Section 3.1.9.)• Loosen the two slotted screws (Fig. 3-30/1) witha screwdriver.• Hold the two reflector module halves -emission module half (Fig. 3-30/2) andexcitation module half (Fig. 3-30/3) together,turn them over against the mounting positionand set them down.Fig. 3-29 Installing Filters and Beam SplittersFig. 3-30 Opening the Reflector Module
